I'm unable to boot Windows 7 after connecting second HDD to SATA ports.
This is what happened:
Experienced slowness while accessing the files and folders. Then system won't boot after restart.
Had 2 Memory Stick. Slot 1 and 3 (out of 4 slots). After several attempts, I figured Slot 1 is having issues. After moving single stick to Slot 2 , I was able to install Windows 7 in SSD (AHCI).
- Single SSD
- SAT Mode set to AHCI
- Clean Windows 7 install on on SSD ( with other HDD removed). Single RAM in Slot 2.
- Booted Windows 7
- Installed drivers ( VGA, SATA, USA, LAN, INF)
- Rebooted several times during the drivers install. No issues.
- Connected second HDD (Install disc removed)
- Booted Windows 7
- Error message - Boot device not accessible.
- Checked Boot Order in BIOS (set to Samsung SSD, HDD, Windows boot Manager)
- Did F2 to check boot order ( shows Windows Manager, SSD, HDD)
Problem 1 : Boot order in BIOS is different from Actual boot order.
After some research, I read Boot order is controlled in MSR. When I rebooted with Windows 7 DVD, things went haywire.
Started System Repair.
Problem 2 : System Recovery options i snot compatible with version of windows you are trying to repair.
Chipset : AsRock z77 Extreme 4.
I'm not sure what else to debug or how to fix this.
Appereciate your help. thanks.

Here's my update after playing around and multiple reboots.
Disk 1 : SSD ( Windows 7 Installed)
Disk 2 : HDD ( SATA for Data)
Looks like Disk 2 is causing the problem. When I boot the system with Disk 1, I can load Windows. After connecting Disk 2. Windows boot Manager error appears with Boot Selection Failed because a required device is inaccessible.
Boot Order in BIOS
Boot Option 1 : Windows Boot Manager ( i tried changing this to Disk 1 - SSD)
Boot Option 2 : Disk 1
