Hi guys,

I have the windows 10 tech preview mounting to a USB drive now for installation. My current setup has a 128gb SSD and a 2TB HDD, with windows 8.1 installed on the SSD. If I was to unplug these drives, and install Windows 10 onto a spare drive I have (200gb Seagate drive), would I be able to jump back to windows 8.1 by simply removing the seagate drive and re-connecting the SSD and 2TB drive?

Thanks

Ok so a few things:

1. The 200gb HDD I have (which I bought earlier second hand for £8) seems to be dead. Spins up just fine but doesn't show up at all on the system.

2. Because of 1 I've decided to install on a separate partition (200gb's) on my 2TB HDD. This has caused:

3. Windows 10 won't install on this partition as it has the wrong file table or something (can't remember the exact wording). Is there anything I can do to fix this without wiping the whole drive clean?

ok to correct my previous post, the error message: "Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI Systems, Windows can only be installed to GPT disks". I quick google search basically said that, to convert the disk from MBR to GPT, I have to wipe the whole disk, somehting I can't do as I don't currently have a drive available to back everything up onto.

Is there anything I can do?

Windows only likes looking at one install table at one time. I installed ubuntu on a drive separate and figured that it was fine to dual boot. Nope as soon as I tried to boot back into 8.1 your installation is corrupted. Partition magic c an work in this kind of situation. Plus if you have valuable data on the drive than why choose that drive to install a new os on? That can seriously cause you to lose the data on that drive. Get another 128gb hd or so to install onto. Or backup your data to bluray disks for a good stable solution.

No. If it is formatted the wrong way, you must redo it in the correct format. Erasing all data on the drive.

Either get another drive and use that, or copy your critical data elsewhere first.
But you can't reformat that drive and save the data currently on it.

This is pretty confusing as I've installed Windows 8.1 before on this drive, heck I think the windows install may still be there. Oh well, tried getting a cheap 2nd hand drive but it was dead. Got a refund but no drive to use :/

It would appear win10 is UEFI only by your description. While you can install one system UEFI and another legacy, ie MBR, you would have to switch in the bios each time when you wish to switch systems.

You should have come to the Linux thread, we'd have fixed you right up.
