Windows 10: Can I install Windows 10 to a separate partition from WITHIN Windows 7/8 desktop?

As the subject states..


Is it possible to install Windows 10 to a different/separate partition from within Windows 7/8/Vista desktop itself?


I am multi-booting and have done it before on a HDD as follows:



1 Drive

7 Partitions

C: Partition 0 = Primary Active & System NO OS Just Boot/BCD/NTLR files

D: Partition 1 = Logical Windows XP - Bootable

E: Partition 2 = Logical Windows Vista - Bootable

F: Partition 3 = Logical Windows 7 - Bootable

G: Partition 4 = Logical Windows 8 - Bootable

H: Partition 5 = Logical Windows 10 x86 - Bootable

I: Partition 6 = Logical Windows 10 x64 - Bootable


Bought a new SSD so decided to do a clean install of ALL aforementioned OS's, BUT NOW,Windows 8 & 10 won't let me do a custom install from a previous version of windows desktop. I now have to boot from windows 8/10 media and I wind up with Windows 8/10 being the C: drive, which I don't want. I want to keep the letter assignments I had before on my hard drive. Has the new Media Creation Tool changed something? I was able to do this in the past extremely easy. I would install XP, then insert Media for Windows Vista and custom install, once Vista was installed, I would then pop in the media for Windows 7 and custom install and so on and so forth. Now I can't seem to do that.


Why has this changed? Why can't I do the custom install from within Windows Desktop itself anymore?


Been at this for weeks and tried everything I can think of,.. also tried a copy of my Windows 8/10 partition old drive with drive letters assignments matching and they WON'T boot. Constant windows wheel spinning and also looked into their registries loading hives and they show correct letter assignments.


I've even gone into the command prompt from the boot install and used Diskpart to assign letters, and still once installed, I check Windows 10 drive letter assignments and it shows up as C: when I've custom installed it to drive H:!! Grrr. Frustrating!


Any help or answers would be greatly appreciated and I'm sure I'm not the only one.

Install windows 10, 7 or both on my desktop pc?!

so. my new desktop is here (the one in my specs list), and although i only got 1x 250gb ssd for now, im still unsure whether i should install windows 7 or 10... i have been using windows 7 until today, but im tempted to give windows 10 a go, to see how it works etc, since i have never tried it properly. on the other hand, im super comfy with windows 7. i know it quite well and im very satisfied with it. i know that im stuck with DX11 for windows 7, but im not the hardcore gamer or so, but i'd like to have the possibility to play future games too, but i can still do that with windows 7, can't i?

so. im leaning more towards installing windows 7 at first and then maybe install windows 10 as a secondary OS. how does that sound? would it work good? i have tried reading up on a recent thread in here about that, and that seemed to be working great for that person.

anything i should remember/keep in mind when/if i choose to have 2 OS on 1x hdd? obviously, i need to install them onto 2 different partitions, but how much space should i allocate for each OS on my 250gb ssd? that way, if i dislike windows 10 that much, i can simply continue with my windows 7 and just delete the window 10 partition.

thanks for any advises on this.

 

Boot windows installation within a partition?

Damnit, I knew thats what you wanted with your first post! I deleted my post because JMCSLOB confused me lol.


Hm, if you Follow this guide (Replace words "flash driive" with 160GB hard drive) How to Create a Bootable Windows 7 or Vista USB Drive for both partitions and then to do a dummy install of windows 8 on the last part of the HDD it should give you the option to boot Windows 7/8 Installer or boot into windows 8.
Edit: On step 4 you will want to make sure you size the partition correctly... or you can use the windows gui tool in control panel.


Once you get that far you can just delete windows 8 from the boot menu using MSCONFIG and delete the partition.

 

Partition SSD during windows 10 install

I'm assembling a new PC and running a fresh windows 10 install. I'd like to know how to partition the ssd into 2 separate partitions during the windows install (I'm using a bootable usb drive to install Windows).

I want to know if I need to input specific settings for those partitions or if it's all automatic?

I need one partition for Windows on and another for my documents. The ssd has 960gb size.

So I'm guessing it has about 60gb over-provisionning. I could leave out a bit more, but it probably doesn't matter that much
