Windows 10: My new Windiws 10 installation is on a non-UEFI drive, what do I do?

I just made a new Windiws 10 installation on my PC, on an SSD. Everything worked great until I formatted the old C-drive. The BIOS can see the SSD, but not as an UEFI, and I’m unable to boot from it. I tried repair, but even that one doesn’t seem to understand. When I go to the command prompt the SSD is set as the F-drive. What can I do to get the BIOS to understand that it should boot from the new drive?

Install Windows 10 using UEFI bootable USB thumb drive

You need to go into you system bios and select allow uefi usb drive. Then add the UEFI usb drive to the boot menu

better way to partition aand create an bootable usb.

For the UEFI system, we can use these steps to create the bootable USB:

1.Locate a 4GB or larger USB flash drive

2.Open Diskpart and run the following command cmd admin type diskpart

• Type DiskPart in the command prompt.
• Type "List Disk” (make note of the disk number of the target USB drive).
• Type "Select Disk X”, where X is the target USB drive noted in step 4.
• Type "Clean”.
• Type "Create Partition Primary”.
• Type "format FS=fat32 quick”.
• Type "Active”.
• Type "Assign".
• Type "Exit".

Copy your ISO files to the drive and reboot

never use UEFI it better to repartition and remove UEFI go with legacy bois

 

Trouble installing windows 7 on RAID in UEFI

As the title says, I'm trying to install Windows on a RAID array in uefi on my Maximus V Formula. When using legacy ROM I can install just fine but I go into CSM and change settings to UEFI only, I can build the array in the UEFI Raid driver (IRST tab in "BIOS") but the array does not show up in the boot menu and when I try to install windows (boot from UEFI DVD drive), The drive does not show up in the Windows install. The next thing I tried was to enable UEFI and legacy oprom in CSM, boot from UEFI DVD drive and install to the RAID array (probably detected by legacy oprom) and it will install. After first reboot, Windows Boot manager will show up as an option in the BIOS boot menu so I set that as first boot device and reboot. I will get to the starting windows screen and then BSOD (too quick to get codes) The last thing I tried was Changing to legacy mode and installing windows to a different drive. once installed, I initialized the Raid array as GPT and rebooted, changed csm back to UEFI only but they RAID array still doesn't show in the boot device list so I repeated the earlier process hoping that It might work because I had initialized as GPT but it still BSODs on starting windows screen. Any help or suggestions would be greatly appreciated

 

Trouble installing windows 7 on RAID in UEFI

I think you were on track with your first try. Windows installer probably needs the RAID driver in order to detect it on install.
