Adding Windows 10 dual-boot (clean install) to a Windows 7 Laptop.
Now that we have the ability to clean install 10 onto a pre-existing 7 machine, and then activate using the pre-existing 7 key...
1. Created a 200GB partition for 10.
2. Booted from USB 10 installer (created today, so latest version).
3. Installed 10 into said 200GB partition with no reported errors.
4. Installer first reboot re-loaded the installer, so removed and rebooted. You'd think they would do something about this, but I'm not holding my breath. Also few walkthrus mention this fact.
5. Boots Windows 7 original bootloader with no sign of the 10 install, so unable to continue on with the setup.
6. Booted into 7 and I can see the installed 10 partition (with no drive letter obviously). Assigned a drive letter and explorer shows Win 10 files are present, and what looks like a bootloader.
According to various sources a Win 10 install will lay down its own bootloader and provide a dual-boot to the pre-existing o/s, in this case Win 7.
As a quick and dirty I used EasyBCD to create a third entry to 10 inside the 7 bootloader, but it throws an error when trying to use that option, something about not being able to verify the o/s.
It should be noted this is an MBR arrangement, a Dell machine, with a separate 20GB OEM recovery partition containing the Win 7 bootloader.
Any "intelligent" ideas much appreciated.
