Windows 10: Bootable windows drive not showing up in BIOS but it works

Hi, I am having an issue after upgrading to a new motherboard ASRock B650 Pro RS. I have two SSDs plugged in: M2 nvme drive Samsung 970 Evo Plus, and SATA drive Samsung 850 EVO. My OS is currently installed on the 850 Evo. However, the BIOS only shows my M2 NVME drive as a bootable option, even though the OS isn't even installed on it. Correspondingly, when I start up computer I get a BSOD saying there's issue with winload.efi file. But if I go into bios, do nothing, save and exit, my OS loads fine from my 850 Evo. In other words, it's working mostly, but it really shouldn't be. What

Multi-bootable USB

Hey guys from TPU, couldn't find any specific thread pertaining to the question asked on title. As mentioned, I'm trying to create a bootable USB, but with many specifics boots available.

I've been trying to create one with multiple boot device including one that enables me to run Windows 10 directly on the USB Thumb Drive but to no avail.

The list of bootable images i'm trying to create are

1. Windows 10 (A full OS running from thumb drive)
2. Windows 10 ISO (Bootable disk image for fresh install)
3. MemTest86+

Have tried YUMI or UUI from the website USB PenDrive Linux but as this is my first time, i don't know how am i screwing up or am doing it right.. Anyone got a rough idea on a step by step guide? Thanks!

 

Hard drive not showing in BIOS or Bootable Drive

I reinstalled windows 7 on my HP laptop and recently installed Windows 10 for dual-boot. Then, my laptop had a Blue Screen of Death (crashed) and it turned on again without booting in Windows 7 or 10 and it didn't even recognize my hard drive. I went into
the BIOS and my hard drive didn't even show up. I created a Windows 10 bootable drive and I tried reinstalling Windows 10 on my laptop and again, the hard drive didn't show up so I couldn't reinstall Windows 10. I have the HP Pavilion g7 notebook.
