USB flash drive after installing CentOS will not start problem solving methodCategory: Hadoop 2014-06-30 15:47 646 people read comments (0) favorite reports Today after the installation of CentOS found the boot file installed on the U disk, so do not plug into the CentOS system, find this method on the Internet to successfully get rid of the U disk to start, to avoid re-use of the USB drive to do the boot disk installation system, simple and convenient, so send a post, save later backup.
1. Open the terminal with the root user into grub mode after entering CentOS
#grub
Grub> Find/grub/stage1
Error 15:file not found
This is my computer, then enter
Grub>find/boot/grub/stage1 Find Stage1
Find/boot/grub/stage1 Find Stage1
(hd0,7)
2. Install the CentOS grub to the MBR
grub> Root (hd0,7)
grub> Setup (hd0)
This is the same as found in the above find. HD0 indicates that the first drive 0 represents the first partition
3. Reboot complete
Grub> reboot
4. Finally use Vim to modify/boot/grub/grub.conf, all (hd0,0) to the same as found in front find, title others changed to title windowsxp, my is XP system is the first partition on the hard disk is (hd0,0).
# all kernel and INITRD paths is relative to/, eg.
# root (hd1,7)
# kernel/boot/vmlinuz-version RO root=/dev/sda8
# initrd/boot/initrd-[generic-]version.img
#boot =/dev/sdb
