My situation is the following:I had a LGA 775 Mobo pc,and one of my father's collegues was upgrading his pc so he gave us his old computer system,i found out that his motherboard had better functions and is better overall,motherboard is gigabyte ga-ep35-DS3L,i installed it in my case and hooked up all devices,booted into windows and it worked like a charm - no reinstall needed.But 2 months ago i bought SSD 120GB,i installed in my pc,all worked great,enabled the ahci mode in bios then proceeded with installing windows.i decided to go with windows 7 as it is my favorite os and i had it already on a usb drive.i've always used usb drives to install os,but i haven't installed os on this pc because the windows 7 installation from my other mobo was working without problems.Okay,plugged the USB with Win7 on it into pc,booted as usb-hdd as it was the only option that would boot from the usb,the loading of windows install files took way too long (like 10+ minutes),so i decided to pull out my Windows dvd and install it using cd/dvd drive.that way it loaded almost instantly and installation went smooth,drive recognized,partitioned it - ssd was os drive,1TB HDD was my Storage.All good to up last night,i decided to upgrade my Windows 7 to Windows 10,downloaded the iso from microsoft using media creation tool and made bootable usb drive with rufus.remember the ahci mode was enabled all the time,even before the windows 10 install.Alright so i booted into usb-hdd and windows 10 began loading installation files,it was really slow but when it loaded the files all became fast and snappy.On the drives screen i deleted the 100Mb system reserved partition and the 111GB os partition from the ssd drive and made new one (as i know the windows 10 uses 500MB instead of 100MB system reserved partition).All good,installation started,fast,snappy,then it was time to restart.System rebooted and BOOM i get message on screen: Port-01: No device found (port 1 is where my ssd was connected to).I was googling for long time,most of the times it was ssd failure.i thought my ssd died and i removed it from my pc,but this morning i thought - well i should try using ide instead of ahci to see if it recognizes the ssd.so went in bios,changed to ide,plugged the ssd back in,turned on the pc and...my ssd was recognized in bios!but that's where the good news end,so the ssd is working,but only in ide,matter of fact im writing this post on windows 10,but i want my pc to be ahci mode so i can use all the advantages over ide,so i went back in bios and set the sata mode to ahci,and...again the ssd failure port-01: No device found.I repeated the procedure and restored the ide mode.
what comes to my mind is: this mobo is kind of old(like all of the lga775) and it doesn't fully support boot from usb like others do,it has usb-zip,usb-hdd,usb-fdd,usb-cdrom,the only one that boots the usb is usb-hdd and it boots slow as hell,after that i removed ssd and put sata to ide mode,plugged in my windows 7 usb and proceeded with installing it.nope,when i reached the partition screen,i made 100GB os partition and rest as storage partition on my hdd (ssd unpluged),installation begin and in the second as it began there was error box,error said : "windows cannot copy files required for installation. the files may be corrupt or missing. make sure all files required for installation are available, and restart the installation.".i know for damn sure this usb is fully working and in perfect condidion,not so long ago i installed windows 7 on my laptop from it,also installed windows 7 on my mum's pc from it-so usb is not the problem.What i think it is,is that maybe the motherboard doesn't support usb boot and recognizes usb as hdd (even when i press f12 for boot menu i have "+" symbol on Hard Drives and under it there is usb-hdd - the only mode that my usb is booted,it doesn't boot from normal usb-hdd mode listed).so basically i think i screwed up something with my ssd-maybe mbr or something else,i am not an ssd expert as i have it for quite a short time.
i will be thankful if you guys help me on this case - i want to restore my ssd so it's recognized in ahci mode,not only in ide,and i want to install windows 10 on it,i will make a bootable dvd drive this time as it's fully supported by motherboard,will not experiment with usb installations on this motherboard anymore,i am scared to go with it actually :d
computer is functioning properly with ide mode,but you know ahci is crucial for ssd and even hdd performance.
