How boot on drive X and restore windows on Drive Y with restore point

Hello,
I have a windows 7 which had problems with windows installer. I paid a company -Restoro - to do it. Stay away from them. THEY ARE CROOKS AND RUIN YOUR PC.
They did a restore point before starting.
On my PC, i have dual booting. I have two hard drive and both have windows 7.
Now, when i select the drive they did work on it, i cannot boot. I get the boot selection menu, i select the drive, it starts with window message and after few seconds, i get Blue Screen Of Death. Briefly, less than a second, then computer reboot itself.
I use the phone and filmed the message, and it was the error 7E.
I boot then in the second drive(i used to write the post now) and when i look in the System folder in the other drive, i can see the restore point file because has the date and time when the "technician/butcher" started.
He got remote acces and i saw he is doing a restore point before it start.
How i can use that restore point to put windows back on the original status before he started to ruin it ?
I have a boot/recovery windows made with windows from that drive. Can that help ?
When i boot with it is just looking for boot problems, but not for restore point recovery. What to do ?
Thank you.

All you need to do is run restore from a cmd prompt you will have to change to the drive and run the restore from that drive by changing folder or giveing fullpath so you dont run it from other drive How to Run System Restore from Command Prompt Windows 7

Hello Samuria
It is a disaster. I disconnected the boot drive and left just the damaged one, plus windows repair disk.
I boot-up on the CD and selected the system restore. The error message was that it is not restore point.
I tried on command prompt. I moved to the drive letter, CD directory to the System Volume information folder.
Did a dir command and show me all the files, including the restore file.
I do not know what to do.
Please help me.
I have a lot of work there and i cannot reinstall all my programs in the working drive. It is a pain , plus time consuming. If i write to a software company and ask to resend the license, , they do not do it on the spot. 2-3 days and more.
I must recover the damaged drive.
Thank you.

There is a MS repair tool that may work Restoro

Will it boot to cmd prompt or boot an install dvd and get to a cmd prompt there or or try fix pc.

What happens when you try and boot with only the 1 drive it may give a clue to the fault which could be disk ,reg or other
