I was trying to repair windows with a boot repair disk and for some reason my bios gave out. Now Everything on my computer is working but i seem to be getting no display and only the fans seem to be running. When i tried to reinstall the bios using the fn+Esc method and renaming bios .fd file to HadesSX64.fd the power light blinks and then the computer slightly does something but turns off after a couple of seconds. I think there is something wrong with how I am updating the bios or if I need the correct bios version please let me know. All I have on the drive is the renamed .fd file and if I put an .fd with any other name on the usb stick it does not seem to give me a register unless it is named HadesSX64. Any help would be appreciated. Thanks.

    Press FN+F6 to try to turn the screen on. If nothing, try to HDMI out to a TV set and press FN+F5 to try to turn the TV screen on.

    The screen doesn’t seem to turn on either of those ways. I have already reinstalled windows by putting the hard drive into an external drive case on another computer and everything should be working but the pc doesn’t seem to do anything but turn on. It’s probably it needs a bios but I am amiss to what is actually going on in this situation and any help would be appreciated.

    Sorry. No. This won't work anymore because the hidden EFI WinBoot partition on the HDD is tied to the mainboard and BIOS chip upon which it was installed.

    Can you boot and see a screen from a USB stick prepared with Microsoft's USB media creation tool?

    I made a fresh windows 11 creation tool on a USB. Didn’t load up as far as I can tell. Still no display and the fans are just running. I am pretty sure it has something to do with the bios but no luck with anything else. Anything I can do to figure what might be going on. Really appreciate the help and any input would be welcome.

    I also tried pressing fn + f6 and fn + f5 after inserting the windows media creation tool but no response. Some sort of visual would be nice. The screen turns on sometimes but it doesn’t really show anything on it and it’s a fairly new screen.

    Sorry no. Win11 currently won't install on your machine. You must use Win10. Also you must tap F12 on startup for the boot menu that allows booting from a bootable  Win10 USB installation stick? Otherwise, default boot  normally ignores the stick.

    There is nothing on the screen so how would I tell it what to boot off or does just pressing f12 load it off the USB drive. Thanks.

    The F12 boot option is a BIOS function which --- if it successfully initializes the graphic adapter output to the screen --- will automatically present the menu on the screen.

    If the BIOS doesn't successfully initialize the adapter, then you should get a black screen (meaning no backlight whatsoever)r. if however you get a blank screen (meaning with a visible backlight), then it may not have anything at all to do with BIOS initialization. It could be as simple as broken conductor in the video cable in the hinge area from wear and tear of opening and closing the lid too much.

    I pressed f12 but got nothing on the screen. There is no backlight so it’s probably something to do with it not initializing. I don’t know what else I can do but load a new bios but simply putting a new bios on the USB stick or aptly renaming it is not giving me to much of a signal. It does do something if I rename it to HadesSX64.fd and then put it into bios recovery mode but I don’t think I am doing something right because it’s not going through with the flash. In a few seconds the computer just shuts down. What would be the best course of action I could take. Do you suggest I use a programmer to reflash the bios possibly? Really appreciate the help and the quick response. Hoping the computer can be up and running soon.

    A couple of times when I was trying to take out the cmos battery the screen turned on but it only showed the light signal there was no actual acer logo or anything on the screen. But that happened kind of spontaneously and then stopped happening. I am not sure what’s actually going on although I can get to the innards of the computer and do little fixes here and there I am not the handiest and would probably not want to mess with too much. Able to do a lot of the stress work but not really inclined to necessarily start taking everything apart. Although if you have a good suggestion I could try to give it a whirl as to a loose connection or something. Let me know!

    Aye! Does this mean the battery pack was still connected when you tried this?

    Battery pack was disconnected when I took the cmos out but I did reconnect it later. The cmos trick didn’t work though since I don’t think it drained and didn’t go back to a system state bios maybe there’s a better way to do it but I did leave it overnight and that didn’t help either. Not sure what’s going on?

    When was this work done? Did the screen seem to work OK immediately after installing it? Was it a dropin replacement direct replacement? Or some kind of an upgrade? And I'm still not sure about the video cable and its connectors with the additional wear and tear they got just replacing the screen, let alone opening and closing the lid thru the years..

    This was done two years ago and the screen was working perfectly fine. But it’s not loading the bios and also the windows isn’t loading on HDMI or otherwise so it seems that the system isn’t loading any of the connected resources. What do you think is a good next step to figure out how I could fix it and if I was to flash the bios what would be the best way to do it. Appreciate the help seriously!

    How was the boot repair disk made? Did you try to run any EXEs from it?

    The boot repair disk was put on a USB and wasn’t able to enter windows pe environment at the time so it simply ran on the starting screen for 20 mins. I tried to turn it off and when I turned my computer on the bios was gone too and windows was already giving a BSOD. I have wiped the hdd clean but now am unable to access anything on my computer including the display and USB drive booting which was working right before. Everything was working before and now nothing is running so that’s very weird not sure what caused all of it. The computer was also giving a no OS found message before it gave out if that helps any.

    Was there any error message on the BSOD? Or was is just a blank blue-colored screen?

    OK. All of this is confusing. Please recap what was done since the last time it booted properly.
    Also a UEFI system cannot simply be copied since the disk must have at least three partitions: UEFI/Boot, main program, recovery. The easiest way to do this is to use cloning software (comes with most SSDs). The hard way is to use something like Rufus to format as a UEFI/GPT disk. I normally use NTFS. Then the signature must be added to the BIOS table. (cloning transfers the original signatures so can skip this).
    Finally use F12 on booot to see bootable devices (must turn F12 on in BIOS).

    It was giving error messages but I can’t seem to recall what they were. It was because the windows had a bad mbr possibly and I was trying to not lose any files but that didn’t workout since I just deleted everything on the hard drive to give it a fresh start instead. Now I just need to reinstall everything on my computer and have it run like normal again if possible. But for that it would need to be able to run anything and right now I am not able to run anything but bios recovery mode. The hardware may be fine but the computer currently has no software on it either and I am unable to do anything on it. So I don’t know how I should proceed. Pretty much I have to reinstall everything on the computer. Bios, OS, etc.
