Windows 7 SP1 failure

Hello guys, so i installed W7 after buying a SSD, everything went well, the windows was updating to sp1 but i didnt know that and i closed the computer to take a look at the ssd's serial number to see if there are any updates (yes, very stupid of me), after i started it again it started updating on the "Starting Windows" screen amd it got stuck at 530-580 out of 96508, and then restarts, the error code is 0x000021a, and then after the restart the bios can't find my SSD, only if i turn it off then back on it will be recognized, i tried reinstalling windows, failed because the ssd stopped being recognized, tried the script.vbs thing, it fails after 10 minutes because it cannot find windows files on the ssd, tried dism.exe, it helps me boot to the Blue screen with "Please Wait" but then it restarts and so on, tried last known good configuration and everything. Plus, when i try to install windows on my HDD, it tells me that (it's 500GB) every partiton (got 2) is made out of 400 gb and has 300 gb free space... Did the sp1 update mess up anything that recognizes the size of my HDD? What's going on????????

Update: i tried to take a different HDD with windows installed and it gave me the 0x0000007B error which is a virus code. How do i remove the virus using command prompt or something else? Cause i don't have acces to the actual Windows. Oh yeah, and the ssd works EXTREMELY slow, it takes me 5-10 mins to get to the system recovery menu in "repair my computer"

Ok, so i guess i am the only person in this world with this problem and i should throw all my PC to the trash, because i cannot reinstall Windows aswell

Thank you for your help but the actual problem was my SSD's (Kingston SSDNow V100 128G) firmware was bad and it is working fine now. My problem was that i could not modify ANYTHING on the SSD (Delete, move etc.). Thanks for the Answers
