Hello guys I have a dell laptop with two operating systems, ubuntu and windows 7,
currently I spend all my time in ubuntu, so I decided to resotre windows 7 to factory image, will it harm my ubuntu?
Dell's factory image will wipe the entire drive and replace it with Windows 7. If you do not want to do this, do not restore to factory defaults
(I've got a dell, did this once by mistake, and hell ensued)
If you're not going to use Windows 7, then I'd suggest just wiping out the Windows 7 partitions and utilizing the extra space as storage (or expand your Ubuntu to use it all), but if you still have a purpose for Windows 7, don't change anything in terms of partitioning.
