U disk version of the DOS boot disk production method
mainly introduces the production steps, methods, and precautions for the U disk DOS boot disk.
Start mode
1, USB-HDD
hard disk emulation mode, DOS starts after displaying C: disk, HPU disk format tool made U disk is Use this startup mode. This mode is highly compatible, but it cannot be started for some computers that only support USB-ZIP mode. (Recommended in this format, this format is the highest.)
2, USB-Zip
Large-capacity floppy disk emulation mode, DOS is started after displaying A disk, FlashBoot production This mode is adopted by the USB-ZIP startup U disk. This model is a singlely optional mode on some older computers, but most of the new computers is not good, especially the large capacity U disk.
3, USB-HDD +
Enhanced USB-HDD mode, DOS is displayed after startup C: disk, the compatibility is extremely high. Its disadvantage is that only the computer that only supports USB-ZIP cannot be started.
4, USB-ZIP +
Enhanced USB-ZIP mode, support USB-HDD / USB-ZIP dual mode start (depending on the computer, some BIOS may start after DOS) Display C: disk, some BIOS may display a: disk) after DOS startup, thereby achieving high compatibility. Its disadvantage is that some computers that support USB-HDD will be launched by using the U disk of this mode as USB-ZIP, resulting in a reduction in compatibility of 4GB or more large capacity U disk.
5, USB-CDROM
Disc simulation mode, DOS can not take up, compatibility is general. The advantage is that XP / 2003 installation can be performed like a disc. When making it, it is generally necessary to produce a specific production tool corresponding to the specific U disk model / batch number, which has a general production tool on the U3 online.
Method
1. USBOOT production: Unpack the USBoot program, plug in your USB flash drive, follow the steps below to make your USB flash drive into DOS boot (Torked for useful data in the first backup USD)
1, USBoot run
1 Select your USB flash drive;
2 Click blue words Select moderate mode;
3 strong recommendation to select ZIP mode!
HDD mode and FDD mode suggestion to try again in ZIP mode;
Zip mode refers to the simulation of the USB flash drive into a zip drive mode, and after the start of the USB flash drive is A
HDD mode refers to the simulation of the USB flash drive into a hard disk mode;
FDD mode refers to the use of the USB flash drive into a floppy drive mode, and the power letter of the USB flash drive is A:, this mode The USB will not find the USB flash drive when it is started on some machines that support USB-FDD startup, so please use it as appropriate.
4 Click "Start" to start making it.
5 When the following dialog box appears, make sure that the data in your USB flash drive is useless, then select "Yes".
6 starting disk production, the following prompt appears, please unplug the USB flash drive according to normal procedures:
Win9x system: Can directly unplug the USB flash drive.
Win2000, XP, 2003 System: Please double-click the "Secure Delete Hardware" icon in the red circle on the right red circle on the taskbar, and unload the USB flash drive.
7 Please plug in the USB flash drive again;
8 will appear below this successful prompt, indicating that your USB flash drive is already on the base DOS, click on the upper right corner. × Close Usboot.
2, put the MAXDOS compressed package in front, release all files inside to the root of the USB flash drive, pay attention to the root directory!
3, here, you already have a good DOS bootstower.
4, start the computer with this USB flash drive: Insert the USB flash drive USB interface (it is best to unplug other unrelated USB devices), restart the computer, press the DEL button on the system self-test to enter the BIOS .
setting (if it is a special BIOS, please refer to which key to enter the BIOS after the motherboard manual), enter the BIOS Features setup, set the boot sequence (start order) to USB-ZIP (or USB- HDD, USB-FDD, please correspond to the working mode of the USB flash drive you make.
two, Ultraiso Production:
1, download Ultraiso, Exe.
2 Mirror file file selection: can be a classic U master two-in-one version of PE (can generate .iso format), or maintenance, myfeng, etc.)
3, Ultraiso launch U disk The method is very simple:
Write the startup disk is as follows: Open - Select the system you want to write - Write a hard disk image - Select the U disk to be written - format - write - ie Can. Select Open ------------- Select PE CD image.
start ------- Write a hard disk image ------- Select the U disk to be written.
Write mode is selected according to the type of BIOS support, it is recommended to use HDD + or ZIP +.
prompt '' burning complete '', pull out the U disk.
three, mass production method:
1, use Chipgenius to query the master model, find the corresponding master mass production tool.
2, entering mass production tools, mass production tools, different types of tool interfaces, not only here. Find a CD-ROM, then you can select the ISO image file, and you can be done.
cmd production
1, first understand the basic command of the CMD:
diskpart // call diskpart command
list disk // List each disk
sel disk * // Select the disk *
Clean // clear the disk, which is all data on the U disk
create partition primary // Create a master partition
format quick // on this disk, format is the system default format
active // activation of the partition < / p>
exit // Exit
2, after some basic commands above, you can start using the command production starting U disk:
1) First use WIN button + r calls up the run interface, enter '' cmd '' in the Run box, in the Open Command Prompt window, enter DISKPART.
2) Enter List Disk (Display all disks under the current system).
3) Enter SELECT DISK 1 (1 is my disk number, 0 is the hard drive comes with the computer, pay attention to the correct U disk according to the size).
4) Clean (clear the content in the U disk, pay attention to the saving before clearing).
5) CREATE Partition Primary (established a primary partition on the U disk).
6) List partition (view the partition on the U disk).
7) SELECT Partition 1 (select the main partition that is just established, one partition number 1).
8) Active (activating the primary partition).
9) Format FS = NTFS Quick (Quick Format U disk).
10) exit (exiting DiskPart).
3, reinsert the U disk. Use WinRAR to open the mirror file and extract the data to the U disk. After the decompression is completed, the system starts the U disk to make it. At this time, restart the selection start item, set the BIOS to install the system from the U disk.
Command line Mode Making U disk boot disk is actually very simple, do not use other specialized tools.
Format
formatting the U disk to right-click U disk icon formatting to perform grid.
If the Virus in the U disk can be operated through a similar product such as Baidu Guard.
Simple repair
for repair data:
repair primary guiding sector (MBR)
repair BIOS parameter block (BPB) < / p>
repair partition table
fix file allocation table (FAT) or main file table (MFT)
repair root directory
is affected by virus
format or partition
error Delete
Data due to data damage caused by power failure or instantaneous current impact
Due to the abnormal procedure Data destroyed by operation or system failure
Unable to start
1, the computer belonging to the computer does not support the U disk start, the condition is allowed, you can try a model;
2, the U disk itself is not properly operational, such as direct insertion, causing poor interface contact, at this time, try a USB interface;
3, U disk quality problem, then only Can replace a USB flash drive or re-enable the U disk;
4, the U disk used in DOS has no driver under DOS, causing the USB flash drive to not be used.
