I installed Ubuntu on an old IBM ThinkPad R40 after trying it out by booting it from a USB drive. Everything worked perfectly, I had no issues whatsoever, so i used the icon on the desktop to Install it. during the install i got a CD drive error, but because i'm using a USB i didnt give it much thought. The isntall completes, and it asks me to reboot.
After i reboot, i get my BIOS splash, and then a black screen with the blinking underscore like the one you see on a command prompt. that's as far as it ever gets. no errors, no error tones, no apparent failure of any kind, it just stops. it was left to sit for sever hours with no results.
since then i've tried installs on multiple different hard drives. i have formatted with ext4 and then tried installing. nothing works. this is the most bizarre issue i've had to deal with in years. i have no idea how to fix this, any help or insight would be greatly appreciated.
[UPDATE] after further reading i see that often people are told to hold down shift to get into the GRUB menu. holding down shift for any length of time has proven completely inefective. if i hold it down during reboot, i get a "stuck key" error, if i hold it down after BIOS splash, nothing happens. nor does Shift-E
