hi all, i have extensively read through out the internet all the methods that i have to use to successfully build up my new system and activate w7. all went well until i have run loader v2.1.7 and rebooted. after that my raid just broke and upon booting, i receive the folloving error: "disk error, press Ctrl+Alt+Del to restart". how would you advise me to get around this problem? system specs: cpu: 3930k mobo: p9x79 ws ssd: 2 x a830 raid0 os: w7 u after some research, i have come to the conclusion that when i installed the os i may have installed from an uefi usb flash disk instead of a normal usb flash disk. i have read that v2.1.7 does not support efi, and i have to convert the disk to mbr, but when i tried to access diskpart before actual os install i had no selection option for my ssd raid array so i just went on with the instalation. my question is: is there any way to revert the changes made by the loader, so i revert to trial state and not to have to reinstall everything and secure erase my ssd's?
