Windows 7: windows failed to start. a recent hardware or software... windows 7

So my cousin wanted his laptop formatted so i inserted the Windows 7 DVD and formatted the 2 partitions that he had created and then deleted them.. so i got 1 full hard drive of 150 GB... then i installed Windows 7 on it...



Then when i tried to boot up i got the error "windows failed to start. a recent hardware or software change might be the cause" and i got some options... i selected continue with windows 7 and then got another message saying "Setup is starting services" and stucks there... i also cant boot via safe mode.... it will load some files but then it will restart and nothing will happen...

I am pretty sure that if i re-install Windows 7 it will show these messages again and again..

How could i fix this problem that im having?

Thanks.

Where did you get Windows 7 installer? How is this being activated?

Try wiping the HD first with Diskpart Clean Command.

In BIOS setup set to optimal defaults. Check SATA controller setting - set to AHCI to try install.
