Introduction to the way of starting installation system with U disk

Introduction to the way of starting installation system with U disk

Many friends of the U disk storage functions are well known, but the U-disk to start the installation system is not understood, now by the small series of methods to introduce the way to everyone.

The motherboard BIOS now supports USB boot and is supported from the motherboard. Start making 1, the first is whether you set the boot sequence, if not:

Insert U disk into the motherboard USB interface (preferably the other unrelated USB devices temporarily unplugged), restart the computer, in the System self-test interface Press del key into the BIOS settings (if it is a special bios, different motherboard coms chip into the bios of different keys, there are press F1 or F12, etc., Please refer to the motherboard manual to determine which key to enter the BIOS, enter the BIOS FEATURES setup, and set the boot Sequence (boot sequence) to Usb-zip (or USB-HDD, Usb-fdd,usb-cd-rom Please work with your USB disk working mode corresponding, in general, support USB-HDD and usb-zip more, support USB-FDD less, also have support, recommended in doing startup easy flash drive when processing into this format, the BIOS can recognize the acceptance of: Driver (ZIP)/floppy disk (FDD /CD (CD-ROM)/also has a hard disk (HDD); First, you set the option by pressing the PageUp or PageDown key on the item. When set, press ESC, return to the BIOS main interface, select Save and Exit (save and exit BIOS settings, press F10 directly, but not all BIOS support) Enter to confirm exit BIOS setup.

Note: Some brand-name machines support the automatic identification of mobile devices and priority to start, you can turn on the boot when the F10 or other keys directly selected, specific see the instructions.

2, the system reboot will automatically boot from the U disk DOS system, the appearance of the boot menu options are as follows:

Boot DOS with CDROM standard features + drive drive

Boot DOS with CDROM + NTFS standard feature + optical drive + read-write NTFS partition

Boot DOS only (No any Drivers) starts only the basic DOS system

REBOOT YOUR pc Restart computer

SHUTDOWN YOUR pc shutdown computer

Note 1: Standard function refers to loaded Himem.sys and Emm386.exe memory driver, smartdrv disk acceleration, mouse drive, Doskey.

Note 2: The basic DOS system refers to loading only Io.sys, MSDOS. SYS and command these 3 dos core files, do not load their

Any of his drivers and programs. Use the ↑↓ key to select the way you want to start, enter OK.

After the startup is successful, the words "DOS LOADING successful" are displayed.

If it is a USB flash drive in zip mode or FDD mode, a a:> prompt will appear.

If it is HDD mode USB disk, there will be a c:> prompt

Now that the DOS system has started, you can do what you have to do.

CD-ROM mode is the latest, can be said to have a promising future. Here's how it's good:

First: Easy to carry.

Second: Versatility is better than using usb-zip and HDD, because the first-CD-ROM is not missing from the bios of the computer's motherboard either before or now!

Third: Usb-cdrom has the features of zip and HDD installed, no need to be afraid of the optical drive or optical disk is not easy to install system failure, do not need to buy a CD-ROM, more importantly, made usb-cdrom than zip and HDD way more secure, optical drive is not susceptible to virus infection.

IV: The Q3 system does not depend on the win system itself.

Note:

1, make a startup disk before please back up the useful data on U disk, it is best to fully format the U disk.

2, there is an NTFS partition of the hard disk or multiple hard disk system, in DOS the hard disk in the order and in the sequence of Windows may not be the same, please find the determination to avoid misoperation.

If there is a problem with the USB drive in use, try the following method:

① to other working modes (ZIP, HDD, FDD);

② Select the other options in the DOS boot menu;

③ change a different brand of u disk to make a new one; (The main chip and storage chip of some USB drives are not recognized and started, but a new class of processing software can be implemented, but the current method is not feasible.) )

④ the U disk to other brands of the computer to try to work properly.

U disk Startup Disk is the main cause of the problem:

① motherboard does not support U disk boot (or imperfect support);

② some DOS software (especially for disk operation Class) can not support USB disk very well;

③u disk is a new hardware after the DOS, the kind of more complex, and the vast majority of USB devices are not under DOS Drive, the current use of the basic is compatible driver, so there are some problems are inevitable;

④u the quality of the disc itself is problematic;

⑤ often on the U disk has incorrect operation, such as 2000, XP, 2003 directly plug a U disk, rather than through the "safe removal of hardware" to uninstall. (This will cause a USB flash drive has a bad block, will appear inexplicable fault.) )
