Win7 boot manager5/8/2023 ![]() ![]() W10 is not that important to me, I just wanted to keep it around just in case (as well as the fact that I might as well get some mileage out of the now useless W7 COA license on it) but I am just not tech savvy enough to figure out how all of these different components are playing/fighting together. I did a reset/re-installation from the troubleshooting menu and everything seemed OK but when I booted into Windows 7 through the boot list it started telling me that it needed to do a disk check, something about NTSF and stuff so I thought what could be the harm? It bricked W10 a second time! Everything performed smoothly but when I restarted Windows 10 could not boot up. Well, things have gone to hell in a hand-basket. (c: - windows 7 os partition, x: - windows 10 bootloader) If you can boot into windows 7, then use bcdboot command to add boot entry to windows 10 bootloader.Īssign drive letter x: to windows 10 bootloader partition before executing the command: Is there no way to achieve this after I boot into either of the O.S.s as they both see all hard-drives in computer-management and seem to recognise that something is installed on each. I can still boot into each one and out of the pale I can suddenly boot into Windows 7 just by selecting its hard drive from the bootmenu (when before it would give me a nebulous error then promptly load W10). Neither the command prompt nor the recovery option from the installation menu can detect anything (even when loading the drivers on the latter). I was only able to get the Windows 7 installation medium to find any of the disks by loading the respective driver from a flashdrive when installing it. If you have problems identifying correct drive letters in windows recovery environment, then post output of Also windows 7 partition might have a different drive letter. You may need to assign drive letter to bootloader partition using diskpart, if it doesn't get assigned automatically. (c: - windows 7 os partition, x: - bootloader partition) Sometimes it can't do it automatically (if there are multiple bootloader partitions). It should allow you adding windows 7 boot entry to windows 10 bootloader. Can someone demystify the process whereby I add Windows 7 to the Windows 10 boot manager because I am aware that it does not work the other way around. ![]()
