13 R1, boot problems
Hello there!
Sorry for my bad english. but i hope u'll understand the problem
I have an issue with my lovely AW13 laptop.
The problem started couple of days ago, when i wanted to reinstall my windows 10 and to change boot mode in BIOS from Legacy to UEFI
Before reinstall Windows 10, i changed all settings in BIOS (i changed Boot List Option in UEFI, instead of Legacy, changed my SSD m2 drive from MBR to GPT and installed windows 10). After installation, i used my laptop for the whole evening without any problems, and turned off it. In the morning when i tried to turn my laptop on, it said that there is no bootable device. Was a little confused, went back to bios to see, maybe something happend to my ssd. But Bios saw my m2 with no problems. Without any changes i restart my laptop and viola, windows started to boot. i decided to rollback everything, cause had no problem with legacy mode, so i convert back GPT to MBR and reinstalled windows 10. again everythings was great until the time i turned off laptop and turned back on. Legacy bios said that i need to reboot and select proper boot device.
So thats how i turn on my laptop right now:
Turn on laptop -> hit F2 -> in Bios press ESC without any changes -> laptop reboots and start boots in windows .
For example if i need to restart laptop, i just pressed it, and it restarts and boots in w10 without problems.
**My ssd is m2 CRUTIAL CT500MX500SSD4 512gb**
What did i try:
Installed fresh BIOS A11
tried to change m2 slot
tried to use another version of windows (7, 8, 8.1, 10)
#P.S.
when i open device Manager, i can see 2 undetected devices without drivers, tried to use special program to find and install drivers, when install was completed, i restarted my pc and it went BSOD with INACCESSIBLE\_BOOT\_DEVICE , and after this only reinstall helped
#P.S.2
when i wanted to update my BIOS from A10 to A11, i tried to do this from Boot device (F12 key-> BIOS Flash Update) but when i chose it, laptop just reboot with nothing. So i used just .EXE file to update bios (but Bios Flash Update is not working even with A11)

Did you disable the Load Legacy Option ROM in the BIOS when you switched to to UEFI? It may not help in this case but it's good to do anyway.
Did you use the Command Prompt to change from MBR to GTP and back again?
I would set the BIOS back to default, format the drive and do a clean Windows reinstallation. It sounds like the system and the drive aren't talking to each other properly so resetting everything should clear the issue.

I reinstalled windows 10 in June 2021, but from legacy to legacy, and I had no issues back then. It’s all started when I decided to switch from legacy to UEFI. Somehow it can’t boot normal even in legacy mode anymore
it looks like alienware when POST can’t see my ssd
It might sound strange , but before POST my laptop keyboard color is different and power button led is off, right after POST the color changes as usual, that’s why I thought maybe it something in BIOS, all diagnostics from diagnostic tool laptop passes with no problems

Yeah, I disabled legacy mode when switched to UEFI, and yeah, I clear the whole ssd by cmd, and convert from mbr to gpt and back right in cmd
i didn’t clear CMOS ( I mean the battery) cause I don’t know will it help
it looks like alienware when POST can’t see my ssd and run windows from it, but right after restart it runs with no issues

UPD#1
I downgraded my laptop bios from A11 to A10, and after couple of tries and w10 reinstalls my laptop boots right in windows 10 after I press the power button(UEFI MODE). But now when im in windows and I press restart, after POST it says that there is no bootable device, and I need to turn off laptop completely and to turn on. Only after this my windows boots.
In Legacy mode it boots only after:Turn on laptop -> hit F2 -> in Bios press ESC without any changes -> laptop reboots and start boots in windows. (but in legacy mode after i enter in windows I can restart it with no troubles )

Hi @nox8315 your initial opening comments were good about converting M.2 drive to GPT partition format which is more reliable and enables BIOS/UEFI fast boot. However there was no mention of creating a clone OS(C:) boot drive as your disaster recovery, should your original OS(C:) boot drive become unrecoverable.
You should consider your disaster recovery options, get different M.2 drive card preinstalled with generic Windows 10 x64 (from eBay, etc.) that can then be updated with system specific drivers, or keep messing around in the hope that your expertise can fix this problem.
As a general rule, never install Dell updates unless there is a new feature you want. BIOS updates should be avoided if your system is healthy. If determined to update BIOS, follow the instructions provided on the BIOS update webpage.
