triple booting windows 7, windows 8 and ubuntu

Does this PC have an EFI BIOS while the other one doesn't? If so then you'll need to enable CSM or Legacy BIOS to be able to boot the other HD or the image of Win8 you apply to the WIn7 hard drive and try to add to a Dual Boot using EasyBCD (click Download - no Name or Email required)

Then if it won't start you'll need to Adjust Win7 to boot on new hardware with Paragon Adaptive Restore CD.

the pc i want triple boot on has a asus RIVE while the other one has a P5Q Pro Turbo, its really old.

i can boot into ubuntu or win 8. but not into win 7 when that hdd is enabled. so i disabled that hdd in bios and i could boot into win 7.

i'll try easybcd.

im booted in windows 7. and i know what hdd the windows 8 in, and the ubuntu installation. do i just add the hdd in easybcd ?

You should be able to boot your choice of hard drives via the BIOS. Set the preferred hard drive first to boot, then if you want the other one use the one-time BIOS Boot menu key to trigger it. On Asus that key is normally F8, but you must tap it before it moves to Windows or it then becomes the Advanced Boot Tools key.

i can't. i had to disable the hdd that had windows 8 and ubuntu on to get into windows 7.

even with boot override it goes straight to wubi ( ? ) boot menu.

what do i do with easybcd?

Install Easy to the Windows that will boot to add the other OS's.

There's information here about how to add Linux: Dual boot Ubuntu-Win7

ok when i boot up the computer now i get to this screen.


and then i press enter on either windows 8 or ubuntu i get this.

for windows 8


and for ubuntu i get this.

Please post back a screenshot of Disk Management - Post a Screen Capture Image.

Perhaps by running a Windows 8 Automatic Repair it will start it and either add it to Win7 Boot menu or reassert the Modern Windows 8 Boot menu. If no boot menu you can install EasyBCD to Windows 8 to add Win7 and Ubuntu. At least you'll have Windows 8 booting again.
