Hi guys, hopefully someone can help me before I kill myself due to frustration...
ok, here goes:
1. I want to make a portable persistent external USB HD on my 80G external HD
2. My CDROM is broken therefore Live CD is no good, that been said, I have created a "USB LiveCD" on my 8G flash drive
3. Removed my internal HD, changed my BIOS boot sequence to USB, got the "USB LiveCD" working, installed on my external HD (not flash drive), installed boot loader to my 80 external HD in the Advance option of the last step of installation... blah blah
4. Restarted without my internal HD, and... nothing... gives me:
"No boot sector on the USB device". When I put my internal HD back, it just loads to Windows... help...
I'm stuck for a few hours here, hopefully you can help me, thanks a lot!!!
here goes my sudo fdisk -l when I was in LiveCD:
