Windows 7: Boot partition only installs on 2nd drive

Boot partition only installs on 2nd drive

Hi,

I've read all about, and understand what the 100mb boot partition is, why windows 7 creates it etc. However my issue is that Windows only wants to create it on Disk1 i.e. the second drive, and not on Disk0 along with the OS. I don't want Windows on Disk1 because my motherboard see it as the second drive and won't direct the bios to look for the OS unless you change it to the boot drive, under the bios settings. the attached screen shot below illustrates the issue.


Someone please explain

Welcome to SF!

Try unplugging the second drive during installation.

If you don't want to reinstall, you can mark Win7 active in Disk Management, unplug the second drive, set Win7 as first HD (after DVD) to boot in BIOS setup, boot into Win7 DVD Repair console, click through to Recovery Tools list to run Startup Repair up to three separate times to rewrite the MBR to Win7 partition.

Next plug the second drive back in, boot into Win7 DVD Repair console tools list, open a command line and type:

DISKPART
LIST DISK
SELECT DISK 1 (make sure it is 100mb SYstem Reserved HD)
CLEAN
EXIT

Now you can partition and format new data drive logical in Disk Mgmt.

I thought about that, but why is it so stubborn as to refuse to create it for Disk0? I mean it doesn't make any sense to have it on the other disk does it?

Mmm my brains a bit tired, not sure I'm getting you. I don't mind starting from scratch but it does this everytime, tried twice already! also only just clocked that its made disk1 active, wtf is it doing that?

You don't have to have the 100mb System Reserved partition. I showed you how to remove it above and recover the MBR boot-critical files into Win7.

Or you can pre-partition before install and you will not be offered the 100mb using these commands.

Boot DVD>Repair console>Recovery tools, open Command Line, type:

DISKPART
LIST DISK
SELECT DISK 1 (for 100mb System Reserved HD)
clean
select disk 0 (for Win7 HD)
clean
create partition primary
select partition 1
assign letter=c:
active
format
exit

Now reboot DVD, select Custom install, highlight DISK0 for install.

Ok sorry, I'm happy to start again with disk1 unplugged and I'm sure it'll go fine but is this the normal procedure, I notice you've got 2 drives Jonathan, did you have to do this as well, or is something with my system just screwed?

If you unplug the drive with System reserved 100mb still on it, it will mess up your boot and not want to delete when you replug it. Better to delete it now using DISKPART commands given above, also pre-formatting DISK0 so no 100mb System Reserved partition will be offered - unless you want one. In that case, unplug DISK1.

I don't mind having the 100mb partition but why is it putting in on my second hd and also making my second drive the active one?

Cannot say why it is doing this, unless you are highlighting second drive when you first attempt to format, then changing to first drive to install.

I would delete the 100mb Sys Reserved before plugging it back in. Use the Diskpart commands given from DVD.
