I have 2 HDDs:

  • Drive A = 80GB SSD with my Windows 7 x64 and a 100MB System Partition that Windows made. Both NTFS.
  • Drive B = 1TB HDD with a NTFS data partition.

Here's what I've done so far:

  • Downloaded EASUS Partition Master Home Edition
  • Made a new 80GB (81920MB) Partition on drive B
  • Told it make an exact copy my Windows 7 partition on drive A on drive B's new 80GB partition.
  • Made the new partition on drive B a "Primary" and "Active".
  • If I take out the SSD (drive A) and leave just drive B it won't boot, I just get a black screen with a white underscore ):

Some other details:

  • If possible, I don't want to format drive B or re-install windows on drive B.
  • If possible, I don't want to boot from the Windows 7 DVD. My DVD Reader/Writer is broken and my pendrive is just 2GB. But, I can borrow an external DVD Reader or something if it's necessary.
  • No encryption is being used.
  • I can download other software (even not-free (as in beer) software) and try to do it another way. Any links to guides, tutorials, etc. are VERY welcomed.

Most of the time you will need to do a startup repair before trying to boot the new drive after you image W7 onto… – Moab Mar 26 '11 at 3:40
Moab and The Journeyman geek are correct. Usually, even if all your partition manipulations worked correctly, you still need to use start up repair to fix the MBR. – ubiquibacon Mar 26 '11 at 3:51

The specific combination makes it a LITTLE tricky - you need to do two things 1) make a image of the current install partition, to a specific partition of your 2 tb disk - most backup software can do this - almost any backup software can do this - i'd suggest something that runs on windows such as macrium reflect free or driveimage xml. A backup method with a restore disk is probably essential for the next bit.

2) ensure the boot sector is installed - many restore disks, including the windows 7 disk do this - however most of these need a cd or some other media. The easiest way is to pop out the smaller disk, run windows 7 or a restore disk (macrium does this) and get it to fix it

you seem to have part 1 squared off.

In short - for part two the easiest way involves a cd or USB
