Windows 10: Install options with legacy BIOS. If I dont ask, I'll never know...

I'm just trying to further my understanding with this.

I always clean install by using the installation media to take the drive in question down to unallocated space, and then create a new partition and install Windows. That works well and gives me the small 'System Reserved' partition and the main C partition. I add other partitions of my own choosing afterwards. All good except that each time I want to clean install I have to first back up all the stuff on the other partitions and then recreate new ones after the clean install and then copy stuff back again.

What would happen if I used the installation media to:

A/ Delete (or format... I'm guessing that's an option from memory) only the existing C partition and for me to clean install into that new space. I would leave the pre-existing System Reserved partition.

B/ As above but this time deleting (or formatting...) the existing 'System Reserved' partition and clean installing. This would leave the small System Reserved partition either empty or I could delete it altogether (so now unallocated).

Is the original 'System Reserved' partition only of use (and only usable) by the original installation that created it ?

Would deleting the System Reserved partiton (my option B above) allow a new similar partition to be created by a new clean install or does that only happen when the whole drive is 100% empty with no pre-existing partitions (such as extra ones I add later).

Difficulty setting BIOS to boot in Legacy mode

Hi,

I read that from your previous link...

That's why I was thinking that a wiped HDD might give a different outcome with the BIOS...

Same reason to try doing a Clean Install with a Flash Drive specifically for Legacy Bios... To see if the Legacy\ Secure Boot issue can be forced to change...

Be sure to have all other HDDs and iOmega stuff unhooked...

I am trying to force something to work on my machine by using a UEFI Flash, as opposed to the Legacy Flash I suggested you try...

I'm trying to boot off of a PCIe based SSD, and my Bios is not recognizing it in Legacy... Not even showing in Bios at all, even though it works fine for Data storage...

 

Powercolor RX480 BIOS required

Is there a way to convert my existing installed Windows 10 Legacy bios to UEFI?

Hi guys, is there a way to convert my OS's Legacy BIOS to UEFI? Reason for this absurdity is I want to dual boot Ubuntu 15 and whenever I disable the EFI setting in my BIOS my usb installer is not detected (obviously). I've searched about it and it leads
me to this article Converting Windows BIOS installation to UEFI - TechNet Articles - United States (English) - TechNet Wiki I just want to know if there are other steps before I follow the article. Thanks in advance.

I wanted to use a VM but my rig can't handle such.
