Absolute newbie here...
Been fighting this situation for last day and a half (on and off...)
Setup:
pretty new machine, runs windows 7, 4GB; HP pavilion a6707, 4GB Ram, dual core (it does have a Nvidia Geforce 7100) which I've seen posts with different issues, but I cannot even load yet..
took HD and put an older 160GB (IDE) HD in so that I would install cleanly Ubuntu from live disk
(unlugged Windows HD (SATA) and plugged the IDE HD (its only one on the bus, configured as Master)
after I ran the install (successfully, no errors show up), when I reboot, I get the " disk boot failure, insert system disk ... pres enter" message
I go through the Bios page, but never get to see a GRUB screen
I've ran out of ideas now, been looking at the forums unsuccessfully, probably my ignorance..
my troubleshooting thus far:
1. changed Bios to boot from new HD, good, it gets recognized, run the Bios test (read, write, etc.) passed all.
1b - changed IDE cable (tried two sets of cables), power plugs, etc. seems to be fine
2a here is fdisk output
ubuntu@ubuntu:~$ sudo fdisk -l

2b . Run this check to see if it worked and so far it checks as per the post

here is output (which matches the poster's 55aa (MBR not locked) and GRUB showing up...
