Hi
1metalguru,
Before you do anything like a clean install or
Repair Install, you should
ALWAYS backup
ALL your important files and folders as well as creating a
System Image. This way, if things go wrong, you will be able to restore your OS back to the exact same state that it was when the system image was made in a very short time. There are two imaging programs which are very popular among members here, the first is
AOMEI Backupper Standard [FREE], and the second is
Macrium Reflect [FREE].
A
repair install differs from a
clean install in the fact that it
ONLY replaces the corrupted OS with a new fresh copy. This means that
ALL your User Accounts, Folders, Files, Documents, Pictures, Music, Videos, Data Files, Icons, and any installed programs are left
intact. It does however,
delete ALL the Window updates, and could possibly affect, sounds, services, visual effect settings and device drivers by re-setting them to default [unusual though]. You
cannot do a repair install at boot, in Safe Mode, using a system repair disk, or using an integrated Windows update disk. Basically, this process can
ONLY be performed from within the
LIVE OS.
I hope this helps!
