Windows 7: Boot sector on the wrong drive

Boot sector on the wrong drive

Hi there, i'm a new member and very glad i found this forum because if you people don't have the answer i probably have to format and reinstall...

I've searched the forum for an answer to my issue and found some things that might be the sollution, but i'm not totally confident it'll fix things, so plz don't flame me for posting an already asked question!

I had a version of Windows 7 installed on drive 0 (schijf 0) it started acting up and doing crazy etc.. so i decided to install a new(er) windows 7 on an another drive, drive 2 (schijf 2).
The newly installed Windows sadly used the old sector for booting on drive 0, so now i get a dual boot option when i put drive 0 first in the bios and a system disk failure with the new windows 7 install, when i put drive 2 first in the bios.

I want to entirely format drive 0 with the old Windows, so now i need to get a boot partition on drive 2.

What would be the best way to do this?


The drives; it's Dutch...schijf 0 is drive 0 and schijf 2 is drive 2.

You'll have to create your boot record using the Recovery Environment.

Either format the old installation first, the 100mb partition or disconnect the drive with the existing installation before starting. Otherwise the RE will keep writing / creating to the old drive.

The easiest way is to add the boot files to the Win 7 partition on Drive 2. Then mark that partition active and set it so Drive 2 is the primary drive in the bios so that active partition is the first one encountered during boot. This does not mean the drive has to show as drive 0 since that is controlled by the SATA connectors.

Open an administrative command prompt window and type the following and enter after, then wait for a response.

bcdboot C:\Windows /s C:

When you have confirmation, close the command window and use Disk Management to set the C: partition active.

Since you have several active partitions, if the Win 7 drive is not set first in the boot order it will not boot.

If you want, the boot file bootmgr and folder boot are hidden system files and can be seen if you set the folder view to see them.

To open an administrative command prompt type CMD in the Start Menu search box and hit
CTRL+Shift Enter.

Using the Windows 7 DVD Repair console, you can deactivate the three Active partitions, clean and format Disk 0 and then mark active to recover the System MBR into Windows 7 partition.

Boot Windows 7 DVD, select Repair on second screen, click through to Recovery tools list, open a Command line, type:

DISKPART
LIST DISK
SELECT DISK 0 (confirm this is the old Windows 7 you want to clean/format)
CLEAN ALL (zeroes HD, deepest clean, takes awhile)
Create Partition Logical
Format
Select Disk 1 (confirm this is Nintendo HD)
List partition
Select partition # (give number for Nintendo)
Inactive
Select disk 3 (confirm this is PS2 HD0
List partition
Select partition # (give number for PS2 partition)
Inactive
Select disk 2 (confirm this is new Windows 7 HD)
List partition
Select partition # (give number for Windows 7 partition)
Active
exit

Now return to Recovery tools list to run Startup Repair up to 3 separate times with reboots as it will attempt to repair before writing the MBR to Windows 7.
