Try these steps again. Post back exact error text and at what step.

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

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

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

What would I adjust it to for a 750 GB (662 GB) drive?

It depends upon what size C partition you want. To use the full 750gb just drop the SIZE specfication, otherwise it's 102400 times how many hundred GB you want for the C install partition e.g. 307200 for 300gb.

Thank you gregrocker for your post. I have the following error when trying to clean the partition 0 (where I have Windows 8 installed):
Forbidden to clean the disk where startup volume is installed

I am not able to chose another volume as it is a big partition of 619 gb
Any suggestion?
Thanks

You can only use the CLEAN or CLEAN ALL to delete all data from the HDD drive, & not from a partition/volume.

Can I dual-boot Windows 8 and Windows 7

Hi Greg,

Can I dual-boot with Windows 7 if I have Windows 8 pre-installed (Single Language and not Pro)??
Pls confirm. If yes, do I need to follow the same steps as you've mentioned in the earlier posts.

Thanks,
Rahul

dual boot

My question is whether dual-boot works if I don't have the Pro edition of Windows 8?
I read somewhere that dual-boot only works with Windows 8 Pro.
