    Download the ISO version of MiniTool Partition Wizard so you can boot with it and do stuff. Boot with that and then select to repartition the whole disk into MBR wiping any partitions. Then use bootable version of Macrium Reflect to restore the system and Windows 10 partition from backup into the disk but this time it will be in MBR mode and will allow you install Windows 7 in the third partition.

    Rather than restoring the whole disk with Macrium Reflect (and get GPT again) you want to restore the individual partitions separately, so the disk remains MBR.
    Okay, here's what's happening now.

    I've managed to install Windows 7, however I need to install the drivers. I cannot use an internet connection, since the driver for the wireless adapter is not installed. How can I get the drivers from HP (link to the drivers is early on in the thread) into my Windows 7 setup? Will I have to use another CD to download all of the drivers (from the internet on my old Windows 7 laptop), then install the drivers from the CD?

    Furthermore, Windows 10 will not start, as to be expected. When I tri to repair install Windows 10, I get this:

    dual booting windows 7 and 10-20151206_165728.jpg

    Message: The drive where Windows is installed is locked. Unlock the drive and try again.

    Any ideas?

    Windows 10 won't boot yet, you must repair startup. But since you have to do it after installing Windows 7, don't bother now. Install Windows 7, then repair startup to boot in 10. Then add Windows 7 with EasyBCD. In Windows 10 the Windows 10 partition (second) should be C, no need to change. In Windows 7, the Windows 7 partition might not be C, but doesn't matter. If Windows 10 partition is not C (asigned to system reserved), remove drive letter from system reserved and assing C to Windows 10 partittion (if not assigned to Windows 7). In either case you cannot change the drive letter of the Windows installation (10 in 10 or 7 in 7). You are only allowed to change the drive letter on the rest partitions.

    Hi,

    Windows 7 is now installed, all sorted except the drivers (which should be ok when I create a driver CD).

    Windows 10 refuses to boot, as expected, saying:

    Your PC/Device needs to be repaired

    The Boot Configuration Data for your PC is missing or contains errors

    File: \EFI\Microsoft\Boot\BCD
    Error Code: 0xc000000f
    If I boot up with my Windows 10 disc, and try a repair install, I get the above screen (see Post 81).

    Any ideas?

    There is a command that moves boot data to another partition, see here. Boot into Windows 7 and run the command to transfer boot data to Windows 10 partition. Or you can try adding Windows 10 with EasyBCD into Windows 7 boot loader (safer).

    Thanks for the info. I'll have to use the command as there is no way I can currently get EasyBCD onto that laptop just yet. The drivers for Windows 7 need installing, and I need to get Windows 10 fixed. I'd rather get Windows 10 fixed first, then I can install Windows 7's drivers.

    You forgot the rule: download drivers beforehand when installing Windows, in case you cannot connect to the internet. Never mind.

    I didn't see an option to download or install drivers though, when I was doing the Windows install...

    Perhaps I should do a driver disc now and install them.

    Out of these drivers: HP Notebook - 15-ac153sa (ENERGY STAR) Drivers and Downloads | HP® Customer Support
    which ones should I install?

    You manually download the drivers from manufacturer before trying a new Windows version or another operating system. From your link, click Option 2: Go directly to the software and driver results. Then download all drivers found (you don't need utilities). Make sure you also download everything in the keyboard and mouse section to enable all key combinations and switches. Needless to say that if there are several versions of a driver, you download the last, unless it has some incompatibility (unlikely) in which case you try an earlier version. All drivers (except maybe the graphics driver) should install in Windows 7 without any issue. You can download the graphic driver directly from Intel's site. Start installing the chipset driver first, as all others depend on this.

    Okay, in which case I should have downloaded the drivers before installing windows 7!

    I'm downloading everything that has "driver" at the start - using the newest version if there are multiple instances - is that the correct thing to do? I don't need anything for the BIOS etc, as I already have a BIOS.

    In the keyboard and mouse section, there was just one driver - for the Synaptics Touchpad.

    Once all this has been done, I can then install EasyBCD onto Windows 7. Will that get Windows 10 bootable again?

    There is only the touchpad driver, but there are several utilities in the keyboard section. Install these also. Yes installing EasyBCD should allow you boot into 10.
