Windows 7: Setup was unable to create a new system partition....

Windows 10 Home x64
Setup was unable to create a new system partition....

okay, so... where to start...

I built a new rig 4 days ago. started installing windows 7 and had nothing but issues. I wanted to install the os on my SSD, but it wouldn't show up in the windows install. I found out that I had to prep the drive and install drivers before I could use it. so I installed the os on one of my HDDs which wasn't easy either. for some reason I had to convert the disk to MBR, after doing so everything went easy. installed the os, downloaded the software and drivers for the SSD, cloned the os to the SSD and continued. then after trying to fix a sound issue something went severely wrong. I tried updating all my drivers and I'm assuming something got messed up. my keyboard stopped working, then wouldn't show up except as a default keyboard. sound stopped working right, games wouldn't load (kept getting a (0xc0000005) error). so I opted to reinstall windows since I figured out how to do it now.... wrong.

so I did end up getting the os to install again, tho this time it said that UEF or EFI systems have to be gpt. I got all the way to cloning the drive to the SSD only for it to say it took it offline due to it having the same signature as another drive. I turned it back on and tried to boot... it was successful except it sat at preparing desktop for 20 min before going to a light blue screen that says "Not a valid version of Windows" or something along those lines.

since then I have tried reinstalling Windows both ways that it worked before and have not succeeded... I'm currently following some instructions on another post to see if that works, but I'm highly doubtful. someone ease rescue me from this nightmare!!!

I can provide much more detailed info if needed

After you installed Windows 7 did you install the drivers that are on the motherboard DVD/CD?

So, it seems as if I was able to get everything installed properly. Got windows installed, cloned to my SSD and most updates/drivers installed without much issue.

I start with installing most drivers from their CD, I did use and install updated drivers for my gfx card, sound, ssd and updated bios.

My OS drive just doesn't look like most screenshots I've seen. It doesn't have the System Reserved or Boot partitions that most UEFI setup drives have. Curious if maybe I will have issues down the road.

Are you installing with service pack included on DVD normally it should see the SSD drive or you can give it drivers during installation. Windows writes a signature to the disk so if you clone and leave both drives in it sees they both have same signature. Swap ports so c is disk 0

No, the Win7 DVD I have must be pre SP1.

My SSD is a PCI card while my other drives are SATA... Is there another way to make it drive 0?

Windows 7 HP 64

I build my skylake computer last June and also had some problems.
I'll give you a general guide. If you need more details, please be free to ask.
- Download the Win 7 SP1 iso - With the MS iso downloader ( download your win 7 brand.
- You have to add the SATA, AHCI, USB 3 and M.2 drivers to the Win 7 SP1 installation disk. Asus has an application to do it.
Read my tutorial Create a Windows 7 USB flash installation with new drives for new MB's
- Once the drivers are inserted to the Win 7 SP1, burn a DVD or use Rufus to make a USB flash disk boot able. Make it UEFI boot able. Rufus - Create bootable USB drives the easy way
- On BIOS, disable fast boot, secure boot and enable CSM (Compatible System Mode). Under CSM, set boot disk priority to UEFI and disable net boot.

Detach all other HDD or SSD leaving on only the M.2 960.
Boot your modified Win 7 SP1 installation disk on UEFI mode, not legacy.
Go to install - Advanced - Delete ALL partitions - create new. It will create 3 partitions.
- UEFI - 100M - Fat32
- MSR - 120M - RAW
- Large NTFS
Choose to install on the large NTFS.

Once installation is over, open device manager and load all missing drivers.

For the updates:

Whelp, I think I will be giving this a shot tomorrow so that way everything is the way that it should be. Do I need to unhook all my other HDDs? I was very intrigued by a post I was reading about a legit way to install windows, customizing the install the whole way thru and I would love to move the User folders as was described in the post. I just want to do this one last time and not have to deal with it anymore. My computer also failed upgrading to Windows 10 today so I'm assuming there are still some issues.

What are the benefits to upgrading to Windows 10? I was discussing my issues with someone from one of the games I play and they highly recommended me upgrading to Windows 10. What would the benefits be if any? Is it worth it?

The only way to tell is to create a system image of your 7 to a separate hdd = so you can restore it later in case 10 does not workout well for you

Windows 10 Home x64

I've done some reading here and there and had windows 10 on my old rig (the free upgrade). But since I'd either have to pay for it now... or use a verify hack, I think I'll just stick to 7. What size USB drive should I get for the installer? 2.0 or 3.0? I don't have anything currently big enough (largest is 4gb).
