i recently bought my friend's computer and he took out his hard drive.
I decided to discard my old pc anyways (except for the hard drive) so i took out the two hard drives and one of the two had windows 7 os already installed into it.

the only thing i had to do from my knowledge was just to connect my hard drive to the computer that i bought, so i connected the two hard drives into the two serial ata ports.

then i chose the boot sequence to the two hard drives i've connected which has the os installed into it, and then boot the computer after saving the bios.

in the cmos it said that the sata ports are connected with the two hard drives
and the advanced settings boot sequence showed that the boot sequence is the two drives.

when i boot it up it would show the windows 7 startup screen, and when the flag (red blue and... two diff. colors) is just about to show up, a blue screen pops up for a split second and reboots and the 'windows error recovery' screen shows up.

when i choose "start windows normally", it does the same thing again and go back to that screen.
when i choose "launch startup repair (recommended)", it would show the windows screen with the repair screen on. after a few minutes of the repair screen loading, the computer reboots again and shows the windows error recovery screen again.

what should i do?
