How to reinstall the system without a laptop
Most current notebooks have removed the "old" settings like floppy drives (including many desktops), and some ultra-thin notebooks have also removed the optical drive in order to reduce the need for volume. Naturally, the requirement for these notebooks to be external That said, portability is achieved, but once the machine fails, the system needs to be reinstalled, and there is no external optical drive available.
Ultra-thin, non-light floppy drive notebooks do not disassemble the hard drive and reinstall the operating system. Generally speaking, there are the following ways:
1. If the notebook supports USB boot (some old models only support USB floppy drive boot. However, although some models support USB optical drive boot, but you can not start using a general optical drive external box, because booting from a USB optical drive requires an external drive The circuit inside the box supports and is compatible with the notebook. This needs to be tested to know), then the easiest way is to take a dual boot U disk and format it into a USB boot floppy disk through the U disk formatting tool It can be booted by plugging into the USB port of the notebook, without having to purchase a USB floppy drive. In addition, if you have a USB mobile hard disk box, it may be useful. Of course, whether it can be used is also related to whether the interface circuit in the hard disk box is compatible with the USB boot of the notebook. Sometimes even if the hard disk box does support startup (OK on other machines), there is still a specific The problem of incompatibility between laptops is not known until experimentation.
It should be pointed out that after booting with a USB floppy drive, there is no problem with partitioning and formatting the notebook hard disk. The difficulty lies in how to get the installation files of the operating system into the hard disk. Generally speaking, boot the system by loading the DOS boot disk with the USB storage device driver For more details, also provide the image file download of the super boot floppy disk), you can find the USB optical drive. However, I suggest that you still copy the installation file to the hard disk first, and then use SYS C: to make the hard disk boot and then boot from the hard disk To install the operating system. This suggestion mainly considers the implied compatibility issues caused by running the installation program through the USB optical drive under DOS.
I have encountered the following troubles. The ultra-thin, matte soft laptop I bought for someone supports USB floppy drive booting, but I do n’t know if my CD-ROM external box does not support the boot function or the notebook itself only supports USB floppy drive booting and does not support USB optical drive booting. Anyway, I have no way to boot from the optical drive successfully. So I thought of booting from a USB floppy drive with a super boot floppy disk that supports a USB storage device, finding the USB optical drive, and then copying the installation files on the CD into the hard disk to install the operating system. Unfortunately, I found that the USB floppy drive can be successfully booted when the USB optical drive box is not connected, and once the USB optical drive box is connected at the same time to boot, then the two USB devices obviously appear like " "Fighting", in short, on this notebook in any way can not make the USB optical drive and USB floppy drive simultaneously available under DOS.
In contrast, after the same boot floppy disk is used to start the desktop internal floppy drive, it can always find the same USB external optical drive and can be used normally. In desperation, I had to boot through a USB floppy disk without connecting the USB optical drive, and then make the hard disk into a boot disk to drive the USB optical drive, and then copy the installation file to install the Windows system.
Another thing to say is that the external box of the optical drive I use is a longevity 088 Forever model with a USB 1.1 interface. After testing, it is used on a desktop computer that supports USB CD-Rom booting. It cannot boot the computer from its CD-ROM, nor does it work on that notebook.
In addition, I cannot use the USB optical floppy drive at the same time under DOS. It should not be because the USB interface (or the total power of the notebook) is insufficient. Because, under the original Windows 98 ME of the machine, you can use both USB optical floppy and floppy drive.
Therefore, that experience reminds us that there is still a hardware and software compatibility problem.
2. You can also consider booting from the PC card CD-ROM drive. For ultra-thin models that do not support USB boot, this may be the last trick to install the system without disassembling the hard disk. However, the PC card drive that supports the boot function is often original (Bootable PCMCIA CD-ROM, the words "Bootable" are too important). The refurbished PCMCIA optical drives sold in the second-hand market are all assembled by JS manufacturers using a disassembled CD-ROM and a simple interface circuit and shell made by themselves. This circuit is "simple" or JS simply does not understand the principle As a result, almost all of these PCMCIA optical drives from 110 to 140 yuan do not support the boot function. So before you start buying, you must try whether you can support the CD-ROM boot.
3. The second-hand notebook market is a hodgepodge. You can find many rare and unexpected objects here. You can always buy the base as long as the starting price. However, for economic reasons, it is best to find a floppy drive that is compatible with your laptop and connected through the expansion port (the optical drive is much more expensive, even if some laptops do not support optical drive startup). The problem of booting up. The common models of old external floppy drives are around 40-60 yuan.
Finally, by the way, the optical-soft interchangeable notebooks equipped with only optical drives should generally support CD booting. If such a notebook does not support CD-ROM startup, you can only find a compatible interchangeable floppy drive from a friend or second-hand market. The processing method is as in paragraph 1, first process the hard disk as bootable through the floppy drive (remember Add the CD-ROM drive to CONFIG.SYS and AUTOEXEC.BAT), then replace the optical drive, and install directly from the optical drive or copy to the hard disk installation.
A friend who just resigned wanted to help someone develop a single-chip application. I helped him buy an ultra-thin second-hand notebook without built-in light and soft, model Panasonic CF-S51 (the classic appearance is extremely low, but the configuration is lower and no Built-in serial and parallel port and external VGA port, configure C2-400 / 11.3 "TFT XGA / 192M / USB, see the Japanese BIOS Setup in it should not support USB boot), Win2000 Pro / mini-Win98 dual System, considering the need to reinstall the operating system in the future, I also persuaded a friend to purchase an external expansion port floppy drive (although the floppy drive can be directly connected to the laptop, but we were lucky enough to find the port expansion of this model laptop The device has VGA / COM / LPT / FDD interface), and the cost of upgrading the additional 128M memory module, a complete set of external expansion ports / floppy drives, and replacing the battery, hey, it only cost 2,000 yuan.
It took about 10 days ago, because my friend opened the length and width, did not expect to provoke the virus back from the Internet, he was too lazy to use the dual operating system brought back, so I asked me to help reinstall Win2000 Pro.
Fortunately, I must ask him to buy a floppy drive! Booting the laptop is no longer a problem, the key to the rest of the work is how to get the huge Win2000 Pro installation file into the hard disk
I used the DOS7.10 super boot floppy disk mentioned in the first post to boot from the external expansion port floppy drive of the notebook. After trying different boot configuration options, only after starting from the third option, the notebook can detect the USB external optical drive And can read the CD-ROM file (you can use it, and trouble to study CONFIG.SYS). So partition / format the hard disk, and quickly copy the Win2000 Pro installation file on the CD to a folder on the D disk of the hard disk.
Next, after making the C drive bootable through SYS C :, boot from the C drive, and then run the DOS installer of Win2000 Pro in the D: drive.
Win2000 Pro was successfully installed successfully.
In the process of copying the installation files and performing the installation, pay attention to the following points:
1. If you encounter difficulties when attaching the USB-CDROM, for example, no matter which boot project you choose, you can't find the optical drive or you can find the optical drive but can't read and write normally, you can also study the DOS7.10 super boot floppy CONFIG.SYS and AUTOEXEC.BAT two files, adjust the control parameters of some of the drivers, the sequence of DEVICE statements, or load other spare USB device drivers in the startup disk to load, maybe it can be solved problem.
2. It's also very interesting to pay special attention to the fact that at some times, the reason why the external USB optical drive cannot be detected is not just as described in the previous point. It turned out that the cleverness lies in the fact that at the moment when the USB storage device driver is loaded, we must grasp the timing and restart the power of the USB external box (the USB connector can also be plugged in and turned on)! If you do not have this experience, and leave the external box open and the USB port is connected, it may still be impossible to find or find but cannot read and write external USB storage devices!
At this point, some well-made device drivers will prompt you to insert a USB device, but the prompt information is always late, and the opportunity to make actions is still fleeting and difficult to grasp. And some USB device drivers that are not friendly enough may not be displayed. So I always close-open the USB external box when the last program loading action is nearing completion to ensure that the USB storage device is successfully loaded.
3. Before copying the installation file into the hard disk, be sure to choose to load a disk read and write buffer program, such as SmartDrv.exe, during the startup process of the DOS7.10 super boot floppy disk; otherwise, the process of copying the installation file will be very long.
4. After the files needed to install the system are copied into the hard disk, there is no need to load the disk read and write buffer program such as SmartDrv.exe when installing the operating system. Remember that when the hard disk starts, it is best not to let the CONFIG.SYS and AUTOEXEC.BAT files on the C drive load the disk read-write buffer program to avoid compatibility issues affecting the installation of the operating system. Although it is all from Microsoft, it is best not to load SmartDrv when installing the operating system, otherwise even if it seems that the operating system is successfully installed, there will be some inexplicable problems when it is available). In the preceding example, I installed the system from the D drive only when there was no CONFIG.SYS and AUTOEXEC.BAT in the root directory of the C drive, so I found no errors in the use.
