Hello guys. One friend give me her laptop Acer to reinstall it. Ok I reinstall it with usb flash drive with windows 7 x86. But when windows finished installation and restarted shows me Acer restore program, i found the sulution of the problem ( format recovery partition ) but when the windows start to copy files from the USB drive i disconnect the USB unawares and after this every time when i get to option for choosing partition for install says me that can't find drivers for the HDD and i can't see my HDD. I need to fix this quickly because i must to give back laptop after a few hours. Please help me. I read some threads about this problem, and now i use KILLDISK to format ALL HDD, but i'm not sure that this will help me. I will appreciate your help really !

Boot from the flash drive. When you get to the start screen go into start up recovery
Once there choose command prompt...
type the following into the command prompt one line at a time...

diskpart
select disk 0
clean
create partition primary
format fs=ntfs label="WIN7" quick
active
assign
exit

now do return to the start install and install windows normally. It should work for you.

Good Luck..

Have a look at this to boot to diskpart.
