Morning all - help me please!

A bit of back story: I have a new build (MSI Gaming M7 Z170 mobo, i5-6600k, 8gb corsair ddr4 ram, kingston hyperx 3k 240gb ssd, 2x western digital hdd). I installed Win7 before upgrading to Win10. All worked fine until one day (yesterday) everything started going incredibly slowly (virtually unusable). At one point, there was an error (reboot and select proper boot device) after restarting and I EaseUS Partition Master reports bad sectors on the SSD. Oddly, though it detected 105 bad sectors while the surface test was running, the end report was zero bad sectors. Either way, I took this to mean my SSD has gone bad all of a sudden, but the plot thickens...

The bad sectors were all blocked together at the very start of the drive, so I isolated the first 10gb and divided the rest 50/50 in to two sectors, so at least one would have no bad sectors. Windows would not install to either one (Error 0x80300024). I formatted my 1TB HDD and tried to install there, but got the same error message.

This suggests to me that it's nothing to do with corrupt drives and the PC is just being difficult with Win7 install. I've heard that Z170 boards are difficult with Win7 installs, but the odd thing is: it was totally fine last time on exactly the same setup!

I'm trying to install Win7 from DVD - legit copy.

Update: I have now read that Z170 boards will only allow Win7 installation if they are formatted as GPT. I converted from MBR to GPT and now get a new message "Windows cannot be installed to this disk. The computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu". So it looks like MBR was better?! Beginning to confuse myself now... I am but a lowly noob. Any advice appreciated.

Please help!
 
Disconnect HDDs when you install the OS and set it to make the SSD one partition. You might need to make sure the SSD is connected to the same SATA port that you used in the initial install. It should also be a lower numbered SATA port than what you are going to use for the HDDs when you reconnect them. It probably wouldn't hurt to reset the BIOS before the install.

Thanks! I had moved the SATA cable to a different one, but moved it back and disconnected other HDDs. I did both at the same time so not sure which one fixed it, but it seems you can only have one drive connected. Once I got back in to Windows 7, I made a Windows 10 ISO and installed with all three drives connected and it went without a hitch. Much appreciated!
