So i wanted to try out linux mint and i install it using flash
drive but i think i accidentally make 1 of my primary partition
into unallocated space which i dunno how i did it(which i think is
the cause of this problem) . So now when i start my pc and the GRUB
appear, i choose windows 7 and it says 'Disk Read Error' along with
a message to 'Alt Ctrl Dlt to restart'. i kept restarting but it is
still the same, i search online but dunno wat they saying coz im
new to it.. Please help if u know how to solve this problem using
linux mint
P.S. I did a backup for my windows. I just wish to load into win 7
and wont mind if my pc no longer dual boot or lose any data.
