I have partitioned my drive to have the option to boot from Windows 7 or 8.

Recently when I power up my laptop it goes through an endless power on, initial boot sequence, black screen with a cursor and repeats the sequence.

Initial Trouble Shooting

  • I'm able to get into the BIOS
  • I've removed and reinserted the battery
  • I've attempted different sequences with the memory sticks and slots (12, 1X, X2, 2X, X1, 21)
  • I've booted off a USB drive with Ubuntu on it and I'm able to see my main hard drive and files.

I'm assuming I'll need to reinstall Windows but I wanted to verify this first.

Based on this is there any other troubleshooting I should be doing?

if you hold CTRL during boot, does anything change? – Frank Thomas Mar 26 '13 at 15:20
It would appear to be the OS is unhappy! – Dave Mar 26 '13 at 16:15

In the end this is what I did. I need WIN 7 to remote into my office so I:

  • Booted Ubuntu from a USB, and manually backed up my data to an external HD
  • Installed WIN 7 and in the process merged the two partitions back together.
  • WIN 8 complained and WIN 7 was not a clean install
  • Booted Ubuntu again, formatted the merged partition
  • Installed WIN 7

In the end, I don't know if the issue was with WIN 7 or WIN
