CentOs install on external USB harddrive


Hi all. Thanks for looking

I've installed CentOS to an external USB harddrive, but the kernel won't boot. It complains that /dev/sdc1 (the partition where the kernel resides) is already mounted on /sysroot. I've really googled this and have not found a solution. I installed Arch to the drive and it booted like a champ.

Any help would be greatly appreciated.

Could there be some issue with an existing hard drive install or maybe incorrect loader to hard drive?

Remove the power or connector to internal drives and re-install Centos to usb. Be sure bios detects usb drive and it should show up as a hard drive choice.

Jefro, thanks for the reply, but I think this is CentOS-centric since Arch installed and booted perfectly to the same drive, using the same Grub on sda.

Finally got CentOS to boot from the external USB harddrive using legacy grub. For those having a similar problem here's what I did:

1. Reinstalled CentOS and wrote grub to the install partition in hopes I could chainload. This failed.

2. Copied the kernel string generated by grub on the external drive into menu.lst on my first harddrive.

Hope this helps someone.
