I have been working on this Windows PC for some time now, and finally have XP, Vista. W7 and W8.1 installed on the 1tb HDD.
Due to XP, I have to use Dos or MBR partioning instead of GPT, and a HDD for the initial install, I can then clone the HDD to an 1tb SSD. After a couple of attempts with some name brand cloning software, and getting errors, I finally booted the PC
swith an old Clonezilla disk I have and accomplished the clone using Clonezilla. I guess third time was the charm.
This PC is set to boot into W8.1, and you can see I also have W10 installed on a 250GB SanDisk SDD. You would have thought
W10 would have picked up the older Windows OS's and generated a nice boot menu, but it did not. I do not want to use EasyBCD,
or keep using F10 for the boot menu. So off to google and search time.

Now how did I get from W8.1 to W10 without using F10, EasyBCD or going into bios and changing the boot order? I used
W8.1 to set the W10 SSD drive to the letter (H), I then opened a CMD prompt as adminstrator and typed this command
" bcdboot H:\windows " I now have a boot entry in W8.1 for W10.One thing is in need of pointing out here.
This is a new install of W10 on a 1 partition drive, if the drive is left unformatted, Windows will then
create a boot partition, C drive partition, and a recovery partition. If one will format and create the ntfs partition
before the install, W10 will then install to that one partition. Hope some Windows users will like this.
