Windows 7: BSOD on command diskpart, rescan, error 0xfffff880009a97e8

Hello i'm new here, and english isnt my main language, so i was trying to read on how to create the BSOD dump file, but how i'm supposed to do that if i can't get into windows 7 to install that software or change anything? My system is complete unacessible. I was trying to recover one harddrive using a case and usb when i found a tutorial saying i should open prompt DOS and type commands: diskpart and rescan but of course im not able to find that tutorial again it's sticky with my windows 7, i'm using dual boot windows xp x64 here now, and the windows 7 crashed after that rescan command, i tried the recovery options and chkdsk it did not fix the problem, i'm thinking as last option to create a triple boot shrink the windows 7 to install another and copy all to there, in case someone can help me here i won't do that as i want recover my windows 7 any suggestions?

Perhaps this tutorial will be of some assistance:

Troubleshooting Windows 7 Failure to Boot

Thanks i've tried most of that, till "9" i don't want to reinstall a copy of fresh OS, i'm sure theres nothing wrong with my hard drive or virus etc it was pretty clean system, the only mistake i did was to type that i did not know exactly what i was doing on DOS all i want is recover my system, i can see everything from the windows xp system my files etc.

I was reading some similar posts with similar problems so i gone to try the safe mode with prompt option to see what it happens, i find out it crashes when it loads the "classpnp.sys" well i dont know what that stands for, anyone could help me out to find out and fix this?

I'm wondering and think i wont get any reply because i know it's very very hard to fix such problem, but in case i just found the tutorial i was following when everything crashed its this:
External Hard Drive won't initiallise due to Cyclic Redundancy Check Error - Please help.

I managed to get mostly of my files back the most important ones was mozilla bookmarks and favorites which i didn't save but did something crazy and got all bookmarks back including open pages from last session so i managed to get some files that i really really need which i took note in sticky notes so i'm pretty happy but if i manage to get the system back is a prize.
