Windows 10 no longer boots in AHCI or RAID after changing driver on RAID storage controller

[dannymurphy12]

I manually changed the RAID storage controller as my Dell XPS 15 laptop was unable to boot in AHCI in order to recognise my SSD drive. Now the laptop no longer boots in either RAID or AHCI. it is stuck in a boot loop and I cannot get to the advanced boot options but I can get to the BIOS and the standard boot options window. I don't have a Windows 10 disk or any kind of backup due to the laptop being new. Any suggestions please??

Burn a win10 disk Download ISO here directly from Microsoft
If you dont have a pc have a friend do it or even use their win10 disk. You will need a blank dvd & burner

or an empty usb flash drive and use the win10 media creation tool also from Microsoft

Once create, use it to boot and run startup repair.
