Hello, I have been having some problems with my laptop recently and I figured I might as well come to the community for some help, as to I have no idea as to how to fix this problem. Okay yesterday I tried to change the format for my hard drives (of which I have four) from ahci to raid. After I turned off the bios menu and went back to the boot process I kept getting the error "Reboot and select proper boot device or insert boot media in selected boot device and press a key", after trying for about an hour to fix this error code within bios I gave up on that route and used my brothers computer to search up the error code and how to fix it. I came upon numerous different posts but none really helped me except for someone saying that you can't really fix it and you need to re-install windows to get your computer back, so I went on the official Microsoft forums and got a download for windows 7 home premium 64-bit the exact version of which I had previously before I started getting the error code. So after using the Windows 7 USB/DVD download tool and making an ISO file I put the ISO onto my USB drive and plugged it into my laptop and after a long process I finally got my computer back!! But of course more <bad language> had to go wrong. Now for some reason even after I correctly set my format to ahci and set the parameters in regedit for the formats to 0, the computer tab now (for some unexplained reason) only shows my main C: drive and it is now bigger 465 GB instead of the 200 something GB I had before on four different drives each. So to recap my actual question at the end of a big < Language again> statement, could someone please tell me how I can get my hard drives back to how they used to be, as in the original sizes and to actually be able to see and use the storage. Thanks for taking the time to read this huge <removed> post and if you could get back to me soon it would be appreciated!
