Windows 7: Windows 7 Ultimate Installer Problem with Bootmgr

Windows 7 Ultimate Installer Problem with Bootmgr

I'm having a problem that is driving me up the wall. I've tried installing clean now 5 times, and it does the same thing every time. I have three drives, two SSDs in Raid 0 (striped) as the first drive, and a 2 TB data drive as the second drive. Both drives are completely wiped and empty with clean partitions. No matter what I do, the Windows installer insists on putting the Boot files on the second drive, which I don't want for reasons too complicated to get into here. I don't understand why when I install to C: (the Raid array) it doesn't put Windows and all the boot files on it. I've tried wiping the drives with diskpart/clean, multiple times and reinstalling. Nothing works. Any ideas? Thanks much.

Temporarily unplug the HDD until Windows installation is complete - reconnect the HDD once installation is finished. This issue affects almost every installation - you aren't alone :-)

May I ask why you are installing to RAID0 which confers no advantages and if one fails causes you to lose all of your data on both? Windows 7 doesn't much like RAID as we see nothing but problems here. I would unRAID the drives and install to only one plugged in alone.

Otherwise as Colin says you need to unplug the HD during install, or predefine an Active partition for install from Step 2 of SSD - HDD Optimize for Windows Reinstallation

Thanks Golden. I can try that later, but is there no way besides doing that? Gregrocker, it seems to improve responsiveness of the operating system (all my data is stored on the second drive so I'm not worried about losing data), but you really don't think there's any advantage?

Anyway, I tried using diskpart, clean, creating a new partition, and setting it active and it still doesn't work. Do I need to mark the second drive's partition inactive?

Why would the data HD's partition be marked Active? Only the OS boot partition should be Active.

So unplug the second HD which is always the best choice. If this is a laptop where you can't easily do that disable HD in BIOS setup, or make one large Logical partition on it which cannot have boot files written to it.
