How to install Win10 on Dell XPS 410 without BSOD using BIOS 'Raid On'
I've have an 8 year old Dell XPS 410 that has had a number of upgrades, to include a new video card and solid state drive. It is currently running great with Win7 but I am probably going to take MS up on their offer for a free upgrade and go with Win10. I've already registered for the upgrade. I plan to do the upgrade first, and then go back in and clean install Win10.
But from my previous experiences with this Dell, there's always been issues with the BIOS setting of 'Raid On' when doing clean installs. Basically, the installation gets hung up because it cannot find the SATA Controllers/drivers that it needs; and it spits out the installation during the middle of it. I've had this problem every time I've reinstalled an OS on this PC (even back when it was practically brand new).
The BIOS only has two settings (the factory default of 'Raid On' which appears to enable AHCI--and 'ATA/Auto Detect--which is not recommended by Dell). In my previous clean installs, I've been forced to reinstall the OS in ATA/Auto Detect mode and then use a workaround. For example, when I reinstalled Win7 last year after getting a SSD, I had to reinstall Win7 in ATA/Autodetect mode and then go back in and use the following link to make the BIOS conversion to the desired Raid On':

But now with Win10, I don't know what the workaround will be. Preferably, I would not go through any workarounds! I'd rather just clean install Win10 and know that it's going to work with the BIOS left in 'Raid On' mode! If I had thought about it sooner, I would have created a virtual machine and tried one of the Win10 pre-release versions. But I believe MS has now cut those off.
So here's the question(s). Does anyone know if I am going to have to use a workaround again? And if so, is there a MS link (as there was for Win7 and Vista) to resolve the issue? If not, would I be able to just install in the non desired ATA/Auto detect BIOS mode, reboot in safe mode and hope the PC will pick up the needed SATA controllers/drivers for 'Raid On' while changing it back in the BIOS?
More than anything, I want to ensure I have full trim command support for my SSD that I installed on this older PC last year. I would really appreciate some insight from others who know more about this topic than myself.
PS There's only two BIOS settings on this PC (Raid On and Autodetect/ATA) with Raid On being the factory default setting. I don't use (and never did) a Raid array.
