I have 2 systems on my PC ,( Lenovo ThinkCenter desk top, HDD 260Go. ) Windows 7 & Linux....
I had a live usb stick 64GB with "Linux Tumbleweed" on it.... So, by mistake when booting on to the stick I messed up something and linux went on to my hard disk
!!
I have looked and looked on the net for info (there's loads that say do this & do that !!) Some say sort out the "grub" first and then erase the linux partition & expande system (C
NTFS.... I'll give you a disk management photo.... Wow !! It's a bit big ... Linux is 35Go+2Go & the 2 NTFS is Windows 7.... If I turn on the PC and let it start alone it opens up on to Linux.... BUT... I cant use or open it because I lost the password !! Silly I know !! ( I do put important things in safe places but sometimes it takes me months to find !! ) Linux is first on the "grub" page & I have to scroll down & click on Windows 
Can aynone help ? Easy & the right help, please ?
