1. Use UltraISO to write CentOS to the USB flash drive, and then copy the two CentOS ISO files to the U disk, the size of the first ISO file needs to be adjusted, cut to 4GB to copy into the U disk due to the limitation of the U-disk FAT32.

2. Install with U-plate, nothing to say,

3. Unplug the U-disk, and after restarting, there is an error missing operation system. In this case, you can start by inserting the U-disk and manipulating it under the terminal:

[Root@localhost ~]grub

Grub>root (hd0,0) # # (hd0,0) is installed in the first partition of the first hard drive. (Will root (hd0,0))

Grub>setup (hd0)

Grub>quit

Then you need to correct 2 device files

1./etc/grub.conf

2./boot/gurb/grub.conf

Will be inside the root (hd1,0) or other because we installed above the hd0,0
