I installed Ubuntu on a different drive to Windows 7, but after installing, Windows 7 disappeared on the boot screen, that is I don't have options to boot Windows 7, the computer start up directly to Ubuntu. Even if I choose to boot from the hard drive Windows 7 is installed, the computer still goes straight to Ubuntu. I checked the Windows 7 drive on Ubuntu, everything is still there, and I know that I didn't do anything on this drive when installing Ubuntu.
When install Ubuntu, I noticed that Windows 7 is installed on sdc, so I installed Ubuntu on sda.
I have tried using Windows 7 installation CD to repair, but it cannot find any windows system installed. Anyway I still performed 'bootrec /FixMbr','bootrec /FixBoot' and 'bootrec /RebuildBcd' under C drive in commmand prompt (cause I know win7 is in C). Then the third command detected my installed windows 7 but when I type Yes to adding it to the boot list, it shows "The volume does not contain a recognized file system".
Then after that Ubuntu also failed to boot, my computer simply shows "missing operation systems". However, I can fix Ubuntu quickly using a live Ubuntu from my installation usb and Boot-Repair. I just can't get access to Windows 7 again.
Here's the link to BootInfo summary from the Boot-Repair. I am totally new on this, would anyone please help me?
