I installed Ubuntu on my laptop today in place of Mint. I was able to boot the Windows drive under Mint, but it failed in Ubuntu with the error described in this page.
However, when I tried to start Windows to disable automatic startup, I got a BSoD with the stop code NTFS FILE SYSTEM. Trying to restart it again after a couple of times selecting Windows from the GRUB, it came to the 'Preparing Automatic Repair' screen which never went anywhere.
How to repair this? The laptop is a Lenovo, so it has a little hole that if triggered with a pin/paperclip etc boots into a menu that allows you to enter the BIOS, boot menu or 'System Recovery'. I tried the 'System Recovery' option, but it then reboots and hits the GRUB, and selecting Windows leads to the same old problem.
I like Linux and am happy with it for most things, but I need Windows to use Visual Studio and Word occasionally. If I have to reinstall Windows, I'd like to recover the files off the Windows partition first.
