I'm really desperate. I installed 12.04 LTS alongside Windows 7.
No Problems. Then Ubuntu did not boot. I repaired the Grub Loader, then both worked nice (though in the Grub Loader it showed two Windows 7 Loaders?). But since yesterday Windows does not boot anymore. The screen just stays black. I wanted to remove Ubuntu with this guide. But GParted just searches and searches and searches. Waited about 2 hours and didn't even show one partition.
Ubuntu itself has problems now. Updates throw error messages etc. Now I just want to remove Ubuntu and have my Windows 7 back. Note that I have no Windows 7 CD (Lenovo didn't send one) and my laptop has no DVD drive.
I have a Lenovo Thinkpad Edge E320.
