So here's the long story, WIn7 updated itself, broke its ability to boot. I use the windows repair session, and that breaks grub. Now I'm running from an ubuntu live disk, have tried multiple times to fix grub by both using the boot repair utility at: https://help.ubuntu.com/community/Boot-Repair That didn't work.

Boot repair returns error message Error : /sda/current_mbr.img does not exist. MBR could not be restored.

Boot Info Summary: => No boot loader is installed in the MBR of /dev/sda. => Syslinux MBR (4.04 and higher) is installed in the MBR of /dev/sdb. sda1: File system: ntfs Boot sector type: Windows Vista/7 Boot sector info: No errors found in the Boot Parameter Block. Operating System: Boot files: /bootmgr /boot/bcd sda2: File system: ntfs Boot sector type: Windows Vista/7 Boot sector info: No errors found in the Boot Parameter Block. Operating System: Boot files: /bootmgr /Boot/BCD

So I now I've tried installing ubuntu a dozen times. The installer hangs on the "Praparing to install Ubuntu" window, after I press continue.

After 15 min of letting the installation hang, I got a popup message. ??? 2125573120 4032594432 4032593920 ???. I press ok, it reappears. I press x, it reappears.

Can anyone offer a possible solution?
