Name of the virus? Error that pops up on the screen?
If you hear beeps (POST) but no raster forms (screen image of ANY kind), that is a critical HW failure.
Can you get into BIOS? If not, there is HW failure which some viruses can stake claim, although rare.
Is the drive bootable? if so, your boot sector is alive and kicking which is half the battle.
Do you see the Windows POTB screen (Pat On The Back... the swirly lights that merge to form the familiar window pane with credit and copyright to Microsoft)? That's a good sign that your data is intact, but unreachable if you stall after this point.
Do you get a BSOD at any time? If so, that means you have passed the HAL layer which triggers Windows, meaning the MS kernel, the smallest Windows building block, is dormant but possibly salvagable.
It is more likely that this virus wiped out your file allocation table, the NTFS equivalent of FAT32. Deleting drive contents takes hours. The data is probably still there, but your partition is damaged. There are several alternatives, none of which are bundled by Windows, but here
is one of my favs.
I'd still make the effort to slave the drive, but be cautioned that if you recover the data, you will also recover the virus and poison your new HDD. Sterilize the drive with Malwarebytes
or even MS Security Essentials, that should do the trick. Again, be best to tell us the name of the virus if you can remember it.
