Can't dual boot Win7 with Win10

[ANUPLUCIFERGAMER]

Hello! So I downloaded the official ISO for Windows 7 Ultimate from a legit site. Anyways, today I burned the .iso image to a DVD and after double clicking it, if opens up the screen to install windows 7.

But the problem is, I can't install it in my any other drives. It shows me some error. And also, if I try to install it in the C drive, it says that my old windows file will be renamed old and I won't be able to use the Old Windows (Windows 10 in this case). What do I do? I want to dual boot this PC with Windows 7. I have Windows 10.

 

Here are some pics:

 

Please help me!

Have you tried to do the Windows install with every other drive disconnected, even go so far as to reset the CMOS too?

Nope. Haven't done that. Will try that in a while.

Use rufus, set it to what you want the filesystem to be ie GPT for UEFI or MBR for UEFI etc, selct the image file and let it write it to the USB. Make a partition if you don't already have one ready. Reboot the PC, if you have the option choose "boot from" when it posts. If not, then enter the BIOS and set it to boot from the USB, let it do it's thing select the new partition or the one you had ready when it asks where you want to install it to

seems like you have to convert the disk you want to install W7 on from MBR to GPT 

here's a guide: http://www.partition-tool.com/resource/GPT-disk-partition-manager/convert-mbr-disk-to-gpt-disk.htm

 

but, I found a problem with having W10 and W7 on the same system, on different disks even

my setup, I select from BIOS what disk to boot

the problem is that apparently the NTFS filesystem on W10 is not 100% compatible with W7's - what happens is that when I return to W7 the chkdsk will immediately find stuff to fix on the W10 drive

so what should I do?

remove the drives, other than the one you want to install W7 on and install W7 on it

 

what I do when I want to go back and forth between OSes, I unplug the power from the other drive

The problem is that you have Windows 7 that doesn't fully support UEFI. and Windows 10 does. So you either need to disable UEFI for legacy OS, and enable CSM, and format everything and install Windows 7, and 10. or do like zMeul suggests

Nevermind what I had posted, my info was out of date, sorry.

@zMeul I converted my HDD to GPT. I forgot to metion this, My case is mini-ITX. And I had an old 1TB HDD. I couldn't connect it to this PC, so i got a External HDD Dock and connected the drive using USB. So that I could use it like any other internal drive.

After converting it to GPT, I made a new partition, again converted it to GPT and again started the setup. This time how ever, it shows the same image( the first image in my Original Post up^^). But the error is shortened to:

"Windows cannot be installed to this disk.Setup does not support configuration of or installation to disks connected through USB or IEEE 1394 port".

you cannot install Windows on a external drive, only on internal drives - you need to (have to) connect the HDD directly to the SATA ports

there is a possibility that it would work via eSATA with something like this: http://www.newegg.com/Product/Product.aspx?Item=9SIA6UM2ES7474&cm_re=esata_bracket-_-9SIA6UM2ES7474-_-Product

Maybe you could also try Windows Home edition, as this is a totally different install to the one already on the machine or as investigation Windows 8.0 - 8.1 if you did not upgrade the WX OS from these earlier versions of Windows ?

 

OR

 

Even try an older installation say Win XP and upgrade that to Win7, although I could not get past the restriction in the BIOS imposed by the mobo manufacturer (am on the X99 platform) with a 64 bit version of XP, Vista may be different ?
