dell inspiron 1545 help

help needed on a dell i got today.. i bought it cheap. due to the fact that the person i got it from was scared of a warning she got a day or 2 ago. on the laptop screen is a police screen saying to pay the fine to ??????? or else, and her ip addy is being logged as illegal.
anyway back to my problem
i thought i would re-install windows 7 as the factory back up has been deleted
on boot up i get the blue screen of death!

i managed to install linux mint no problem at all.
i try windows again and blue screen again

tried maxtor powermax to low level and kill disc

any help appreciated guys

if this post is not allowed i apologise now but im at my wits end with it

sorry thought it would be better posted here.

Unplug all other HD's and peripherals,

Boot into BIOS setup, reset to defaults, save changes. If an EFI BIOS, enable Legacy BIOS or Compatibility Support Module, set DVD drive first to boot, HD second. Then set SATA controller to AHCI. Save changes and Exit.

Then boot into Win7 installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here.

At first installer screen Press Shift + F10 to open a Command Box, type:

DISKPART
LIST DISK
SELECT DISK 0 (after confirming Windows 7 target HD #)
CLEAN
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE
EXIT
EXIT

Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt.You are creating the partition here for the purpose of marking it Active which overcomes certain install failures.
