I've had a Win 7/BackTrack dual boot install on a HDD and was migrating to SSD. The Win 7 migration couldn't have been easier, just a few clicks in Paragon Disk Manager; however I couldn't find an easy way of migration for BT/Linux so I decided to do a fresh install. The install seemed to go fine but when I rebooted I got an error "No Operating System Found." Any idea what went wrong or how I can recover? I'm pretty sure I can use a Windows Recovery Disk to get Windows back but that won't help me with BT or how to keep that from happening again if I do another install.

Sounds like an issue with grub (or whatever boot loader you installed). If you boot with a live CD can you still see all your data? I'd check that first. There are some pretty easy ways to migrate data if you'd still prefer that, tools like clonezilla can copy one hard-drive to the next, you can make tarballs of the 'important' stuff or use dd (within linux/live cd) to copy disks, partitions or data.

Okay, so as long as your data is there please run http://bootinfoscript.sourceforge.net/ and supply the output. This will give me an idea of what your system looks like and where the issue is. If the output is too large to post use pastebin or some other tool.

OK, will do when I get back home Monday. Thanks for the response.

If you had an existing installation of wins7/Bt clonezilla-live-cd/dvd/usb would've been a perfect solution.
If you still have those operating systems store on original hdd try it.

I found out that you can't directly clone a drive/partition to a SSD, something about "partition alignment" but that if Linux partitions are properly aligned, which is most easily done in Windows, you can use fsarchiver to back up the original system then restore it to a new partition as it respects alignment. What I've done now is:

1. Use Paragon Disk Manager to migrate the Win 7 OS on HDD to SSD, filling the entire drive.
2. Use Windows Disk Management to "shrink" the Windows partition by the same amount as the size of my BT5 and swap partitions.
3. Use Windows Disk Management to partition the newly created unallocated space into two new partitions, one for BT5 and one for swap.
4. Use GParted to format the BT5 partition as ext4 and the other as linux-swap.

I've gotten that far and have burned a "SystemRescueCD" that contains fsarchiver but found it is strictly commandline driven, no GUI, and I'm at a loss as to how to use it to backup and restore my partitions--what I've read so far is Greek to me.

Can anyone help this newbie with fsarchiver?

I was finally successful in migrating my Win7/BackTrack5 dual boot installation from HDD to SSD using these steps:

1. Use Paragon Disk Manager to migrate the Win7 OS on HDD to SSD, filling the entire drive.
2. Use Windows Disk Management to "shrink" the Windows partition by the same amount as the size of my BT5 and swap partitions.
3. Use Windows Disk Management to partition the newly created unallocated space into two new partitions, one for BT5 and one for swap.
4. Use GParted to format the BT5 partition as ext4 and the other as linux-swap.
5. Use fsarchiver (on SystemRescueCD) to backup BT5 partition (to USB flash).
6. Use fsarchiver to restore BT5 onto new drive.
7. Boot with BT5 Live CD and install Grub.
