Windows 10 upgrade failed HELP!

photodgm

Trying to upgrade desktop PC from Windows 7 to Windows 10. I think it got to configuring drivers (had restarted at least once) I now have a light blue screen with the following.
Recovery
Your PC/Device needs to be repaired
The operating system couldn't be loaded because a critical system driver is missing or contains errors.
File:\windows\System32\drivers\iaStorA.sys
Error code: 0xc0000359
You'll need to use recovery tools. If you don't have any installation media contact your PC administrator or PC/Device manufacturer

Press Enter to try again
Press F8 for Startup Settings
Press F9 to use a different operating system

F8 and choosing safe mode also F9 get me back to this screen.

Any help much appreciated.

iaStorA.sys is the Intel RST (Rapid Storage Technology) driver; guess its old or corrupt? (not sure why the install doesn't pull in the latest one.)

Best option is to restore to your previous Windows7 build. Do you have an image? And ensure iaStorA is up-to-date. Could try a Windows 10 Startup Repair (needs W10 boot disk/USB).

I have a Win 7 restore disc - there doesn't seem to be a clean way of shutting down from this screen. I think tis is a Win 10 screen it doesn't look like previous blue screens I've come across.
So is the order?
1 turn off PC
2 turn on PC press F10 to get into bios
3 change order of boot to CD then hard disc
4 put disc in drive
5 exit bios
6 hope win 7 boots
7 update iaStorA.sys (any idea how?)
8 try win 10 upgrade again
Thanks for responding.

Re. iaStorA - I meant check it before trying W10 again - if it worked with W7 before I'm sure it'll be fine again. If you have W10 media you could try booting from it and doing a Startup Repair (depends how far the W10 install got I guess).

I got this blue screen after about 30% of the win 10 update - no media just the windows down load from Microsoft.
If I have to boot from my windows 7 boot CD my original windows 7 installation should still be on my hard disc - so can I make the computer boot from that rather than try to use the failed win 10 operating system?

grumpycrab

Yep, try your W7 boot media; W7 should still be the default boot OS.

Thanks - I'm back in Windows 7. The Intel rapid storage seems to be working fine. So I now need to think about how to upgrade. Since the driver works fine under Win 7 it isn't missing and unlikely to contain errors - possibly this version has some form of incompatibility with Win 10. As it is a system driver I think it might be quite chipset and mother board specific so up dating could be interesting!!!

Upgrading from MEDIA is more reliable than Windows Update. Ensure you have your important stuff backed up.

maybe consider moving to the Microsoft AHCI driver before trying again, or update to the latest RST drivers.

Are you using RAID ?

If you don't understand the question then I'd suggest you are not and you do not need iRST. Get rid of iRST BEFORE you again attempt to update to W10 and reboot.

The Intel AHCI driver is not the iRST driver, iRST is Intel's RAID driver.

The Intel AHCI driver is not the iRST driver, iRST is Intel's RAID driver.

It is a form of RAID. It is a small SSD that 'accelerates' system files on the main hard disc it was only being used for a short time when SSD were very small and expensive.
