Dell XPS THX 8300

Windows 7 with Windows 10 Upgrade

I deleted a user account on the computer. When I did a restart it went into a BSOD loop.

Windows Error Code 0xc0000001

INACCESSIBLE_BOOT_DEVICE

BIOS Error Code 2000-0151 Validation 199661

Dell told me it is the hard drive. Any other solutions??
