Win7 boot failure, DVD unable to reinstall/boot

ok ive tried:
- replaced the Vid card with my old faithful 880GT (the one im using on the puter im typing this on), there was no change in how the boot failure occurrs. So the vid card isnt the issue. GTX275 is now back in the system.

- ive removed the data HDD jumper /power and 2 of the 3 ram sticks.

- Made a USB win7 OS bootdisc from a 64bit image file downloaded and used the windows USB boot disk creator exe. This was done on a vista 32bit machine but im thinking that shouldnt matter. When i selected to load from USB using F8 on startup/bios, i get the single line error along the lines of: 'boot partition unavailable or corrupted' at which point it stops and sits there on that black screen with the above line and a flashing cursor. (have to turn off or hard boot) I can confirm the exact wording of that error line if needed. IS this error pointing at the C; with the OS install on it or at the USb bootdisk i created??

-windows mem test in the system recovery menu. But it doesnt give any results on restart because w7 doesnt load .obviously.

currently i'm trying memtest86 on a single stick of ram in slot0 via a usb boot, letting it do the 5 pasess. Will post results when done.

ok well having done some searching it may matter that im trying to create the USb boot from another machine thats running vista 32bit. But theres no definitive guide our help around that lays it all out step by step for this scenario.

anyone able to assist?
I'm trying to make a usb boot for my broken W7 64bit system, using my older vista 32bit machine. I used the straight download creator tool from msoft but it gives me the "Invalid or damaged bootable Partition" error as a result.
I suspect i have to do something fancy with bootsect and manually make the USB boot drive but really dont know where to start . (and after all that i dont know if it will help with being able to resurrect my win7 OS anyway)

hate to tell you but I am pretty sure you cant make a boot for a 64 bit system from a 32bit system the architecture is too different

hmm....i found a random post with this workaround..... legit?:

bootsect from W7×32 .iso will only run from x32 bit system.
bootsect from W7×64 .iso will only run from x64 bit system.
To prepare W7 x64 from a x32bit system:
1) download BOTH W7×64 and W7×32.
2) Mount your W7×32 .iso.
3) run bootsect /nt60 Y: (Y is drive latter of your USB drive ) from W7×32 .iso, to prepare your USB key.
4) Now unmount W7×32 and mount W7×64 .iso
5) Extract W7×64 to the USB key.
6) Boot from USB.
Bootsec will prepare USB the same way, regardless of x(bits).

the fact that i cant even use the oem dvd for recovery at this stage.. is it even worth trying a USB boot? or is it time to conclude that the SSD has packed it in.
(current memtest pass 2 and no error with the stick in slot0)
and if so, is there a way to just completely wipe the disk from command prompt as a last desperate measure?
I have a new out of the pack seagate 1tb HDD ready to go in its stead but i dont want to write off the SSD as failed unless it really is and ive exhausted other ways to get a repair going.

The RE used for the System Repair disk is different in several aspects from the PE used by the install DVD.

Both will enable you to access the repair console.

Humor this old man. Boot from the System Repair Disk.

Did you boot successfully?

If yes, the microsoft memory diagnostic is also available at the System Repair Disk console.
