First time building a PC.

Using a Gigabyte Z170XP motherboard. Upon first boot, it says "Reboot and Select proper boot device, etc."

I'm booting from a SSD (Radeon R7 240GB) that I was just using on my old PC an hour before (it was working completely fine). I had a look around in the BIOS and made sure it was booting from the SSD; it was.

I unhooked everything except the essentials and the drive, but still the same issue.

Any solutions, without having to reformat the drive?

Perhaps your old PC wasn't using the new "UEFI" which is the replacement for the old "BIOS"? UEFI wants something different on the drive compared to what BIOS wanted. There should be some sort of compatibility settings in the UEFI/BIOS menus of your new motherboard. Perhaps you have to enable that manually on a very new board like the one you have, so take a look around.

What you want to look for is a screen that has options named like this:

"UEFI boot"
"Legacy boot"
"CSM" = "Compatibility Service Module"

You should also make sure that your boot order actually includes disk drives and you can try making sure that drive is listed as the top (both of the general order and for the order of disks).

I think some motherboards want you to connect your OS drive to certain SATA ports, but I think that has to more with speeding up the boot time than anything.

I see something called "Storage Boot Option Control" that has a drop-down list containing "UEFI Only", "Legacy Only", and "Disabled". I've tried all 3 options with no success. Also tried it with and without CSM Support, but I don't know what that does exactly.

Hmm, I don't really have too much experience with this. There's always the option of trying to repair the boot sector on the drive (it's one of the windows repair options booting from a CD), but it doesn't seem like that would help.

I had a look around in the BIOS and made sure it was booting from the SSD; it was.

How did you verify that?

I'm wondering if it might be a more simple problem like a cable not plugged in.

Under "Boot Option Priorities", it says "Boot Option #1". I set Boot Option #1 to my SSD.

All the SATA cables are secure, to my knowledge. I just checked.

you can't boot from a blank(or seen as blank) ssd/hd.
you very rarely can boot from a ssd/hd that had a system install on it based on another pc(you'd need some serious old-motherboard to new-motherboard compatibilities).

get a bootable win cd/dvd/usb and reinstall everything on your ssd

Good to know. Thanks for the info.

I'd just try a windows repair first before going through a full reinstall. You'll probably need to boot into safe mode to uninstall the old mobo drivers and install the new ones if you get that far.

New to me as UEFI installations require my PC to boot from the boot manager rather than directly from my SSD. Is that the case with everyone else?

You can have one of the entries in the UEFI boot manager marked as a default that will be started at boot automatically. I don't know of a Windows software to configure that, but I think for example Windows 8.1 and Windows 10 already force their entry as the default whenever they are booted into. Perhaps the boot repair feature on the Windows installation media also sets that, so maybe running that once would fix a problem about this.

I know there's a lot of laptops that have a weird UEFI that doesn't fully follow the standard and ignores things that the OS tries to configure.

Haven't touched my computed in 1 week. When I opened it today, the first thing I realized is that it took about 1 minute to boot (I have a SSD : Samsung Evo 840, 120 gb).

Is it because my SSD is dying? What can I try to fix it?

Do you have the firmware updates for the 840 evo? There's a pretty big issue with it, especially if you don't have latest firmwares.

Yeah, I just updated to the latest Firmware

I'm cleaning up the SSD. Maybe it will help.

The performance drop is huge. I've reseted my OC and BIOS. I updated my BIOS. I'm removing programs. So far, no results.

Everything was fine last week

That test shows extremely low read IOPS, not sure why that would happen

Ok, I managed to fix my issue (temporarily?)

I tried with old RAM : same results

I removed my non-OS HDD (an old 300 GB Hard Drive) : Everything was back to normal

I replug 300 GB HD : Boot time goes back to 60+ seconds

I removed my 300 GB HD : Boot time down, good speed

I put back my old HD : Boot time goes back up.

I switched the SATA cable, no changes

I switched my old HD to SATA #3 : The boot speed is back to normal

I tried SATA #4 : Boot speed goes back to 60+.

At the moment, my two HD (SSD + old HD) are sitting in Diagonal (SSD in #2, HD in #3)

This looks very strange. I am unsure if my solution is permanent, or just temporary. Any ideas?

I noticed something, not sure if that could explain why i have such low readings :

My OS is installed on an IDE setup. I think some websites suggest AHCI

It would require a reformat to fix this right? If there's a way that doesn't involve reinstalling, I'd like to try it!

You can change it in the registry IIRC but you should have set that before installing windows

you may also have multiple sata controllers doing something weird, i have two different sata controllers (one from intel, one from another company) on my motherboard and only the intel one plays nice.

The Speed is fixed!

Wow, a big difference. I manage to find a way to change IDE to AHCI without reinstalling windows

I'm going to test my boot time. Hopefully, it's fixed...

That's good, how did you change it to AHCI?
