Question: So i was at my pc, but then it just froze, i restarted my pc, and got Reboot and Select proper Boot device or insert boot device and press a key. So i restarted my pc few times, went to Select boot option but my hdd was not there. I checked Sata cable connecting to hdd but its not unpluged, luckily i still have Ssd connected where i could try to install my windows. Should I do that?
Answer:To answer your question : yes you should run windows from an SSD to gain max. performance.
For the HDD i’d say try a different SATA connection. If that doesn’t make a difference you can check your BIOS to see if it detects the HDD at all. If not then the HDD might be dead.
Also do not forget to use the right SATA cable for that HDD (6Gb/sec). If you have a normal SATA cable then that cable will burn up and litteraly melt from the inside when used with a faster SATA device like your HDD.
