Windows 7: change system hard drive

change system hard drive

hello all!
i encountered a problem after installing a new hard drive
i have 3 HDs (including the one i just installed) C: wich is where windows is installed and E: and F: for data
after installing the new HD ( F: )and formatting it, my system stopped booting, it just hangs, so i changed the boot order and it boots fine, but not through C: but through E:
i also found new BOOT folder in E:, wich wasnt there before
i believe that the HD the system boots from should be the one Windows is installed on ( C: ) so if im not mistaken (very likely i am) i should have C: marked as BOOT and SYSTEM in the Disk Management window
i searched a bit but cannot find a way to fix this, help would be greatly apreciated!

this is a screenshot of my Disk Management window

Welcome to the forum, I don't know enough to help but I did notice from your screenshot that you have 2 Active partitions so perhaps that is the problem. Wait until one of the experts comes along to help I just wanted to welcome you and point out my observation.

thank you for the warm welcome, its helpful in a way to

also, i should have mentioned that initially just E: drive was active
both of them being active is a result of my attempts to fix this
didnt think it can have an effect but ill try having only C: active and report back

Hello zuth, welcome to Seven Forums!

My friend Joan is on the right track.

Since the Hard Disk Drive that shows as Disk 0 is marked as Active, set the Windows 7 (Disk 0) as the first boot device in the main BIOS again and boot the Windows 7 installation DVD or a created repair disk and do the 3 separate startup repairs with the separate restarts to recreate the "System" boot files to the Windows 7 partition, have a look at this tutorial at the link below.

Startup Repair - Run 3 Separate Times

Then have a look at Option Two #2 of the same tutorial to see how to mark the Disk 2 as Inactive so this can't happen again and be sure to post back with any further questions you may have and to keep us informed.

I suspect that the MBR is pointing to E as the boot partition. No idea how that has happened.

I suggest you deactivate E and fix the MBR. Both can be done with the bootable CD of Partition Wizard (last download on this page) Free Download Magic Partition Manager Software - Partition Wizard Online

hi, and thanks for the quick reply
i tried your suggestion, changed boot order to C: ( disk 0 )
but when attempting "startup repair" it cannot detect any problems
also tried making disk 2 ( E: ) inactive and than running "startup repair" while disk 0 is first boot device
no good, it just hangs whenever i try to boot from C:
had to make disk 2 active again so i can boot my system

maybe im missing somthing in the "startup repair" phase?

Power down the PC and disconnect the HDD data cables from the motherboard, leaving only the Windows 7 HDD connected, make sure it's set as the first boot device in the BIOS and try the 3 startup repairs again.

You are doing at least 3 separate startup repairs with system restarts between each repair?

gonna try this in a minute.
just to make sure im not doing it all wrong.
im starting the system with windows CD in and clicking repair, then "startup repair"
then it tells me that are no problems, restarting and repeating, i should then still do it twice more? and again get no problems?

With only the Windows 7 HDD data cable connected to the mobo and set as the first boot device in the PC main BIOS, boot the Windows DVD and do this 3 separate times with a PC/system restart between each startup repair.
