Dual-boot conundrum

I’m running Windows 7 on my PC’s main SSD drive, but prior to the upgrade offer ending, I cloned the drive to another disk and upgraded that to Windows 10. However, if I want to boot into Windows 10, I have to disable the SSD drive in my PC’s BIOS for it to boot. Can you help? [JAMIE MARSHALL ] Matt Hanson replies: We identified Jamie’s PC has having an older nForce motherboard, with no option to choose a boot device when starting his PC. Newer PCs have an option to choose the drive to boot from, which he could have used to switch between the two. The problem is that Jamie made an exact clone of his original drive, so the second drive has its own bootable partition, and neither drive’s bootable partition knows the other version of Windows exists. As the SSD drive is the current default for your PC, boot into Windows 7 from that. Next, take an updated drive image using Macrium Reflect ( www. macrium.com/reflectfree.aspx), just in case.

html to download the tool for fixing your dual-boot problem, then select the Dual-boot Repair Tool 10 link. Save the zip file to your hard drive, then extract its contents and run DualBootRepair.exe. Choose ‘Automatic Repair’. You should see that both versions of Windows are detected. Click ‘OK’ followed by ‘Run’ and the repair should be performed. You can verify this by clicking ‘Start > Run’, typing msconfig and hitting Enter, then switching to the Boot tab. You should see two entries, with the Windows 10 entry set as the default (change this to Windows 7 by selecting it and clicking ‘Set as default’). Reboot and the fix should be complete.
