I recently needed to upgrade my system that had two 80GB drives in a RAID-0 array for my operating system to a 1TB single drive. I used Acronis TrueImage to clone the array to the new drive, then removed the 2 small drives. At boot-up I get a blinking cursor, then "Insert Boot Disk" message. I am able to boot off of the CD that I created in Acronis, but not without it.
(The RAID was made using the onboard utility of my ASUS M2N-SLI Deluxe motherboard.) In the BIOS if I try to disable the RAID for the SATA ports I get nothing, not even an option to enter the boot disk.
I decided and to go ahead and make another RAID-0 with 2 larger Raptor drives. All was going well, but over the last couple of days, I have been having problems with programs having "Missing License" files and am unable to restore from backup.
I think it is time to break down and get my machine to a knowledgeable professional.
