I have two HDs, in one there's a OS-less NTFS partition which I sucessfully shrunk using Linux's gparted utility. On the other drive, I have Windows 7, which since the resize, will only boot on one each four attempts if the former HD is turned on.
If it's turned off, it will always boot correctly.
When it doesn't boot, screen goes all black but the first row, where I can see some random blue pixels. Sometimes with control + alt + supr this screen disappears, proceeding to the login window.
On successful boots, the shrunk partition is fully recognised by Windows.
What is it exactly going on here and how can I solve this issue?
