I have a system with SSD and HDD. Windows is installed in the SDD and HDD is for data. In the last disk is where I installed Manjaro.
I created 4 partitions:
/, /home, swap and /boot/efi (the installer was the one who pointed out the need for that partition).
After the installation I rebooted the pc but grub didn’t show up, and the Windows system started.
I rebooted again to try to enter the BIOS, but now the BIOS doesn’t show up. It is just a black screen with a “_” in the upper left corner of the screen.
I don’t know much about linux. So is there a way to fix this? I don’t care losing the Linux system, I just want the BIOS to show up again.
My pc is an Acer Nitro 5, btw.
- start pressing F2F2F2F2F2F2F2F2F2F2F2F2F2F2F2F2F2 the moment the screen turns on until you’re back into the UEFI settings.
Thanks, but I already tried that. As I said in the post, it just shows me a black screen with a no blinking cursor at the upper left corner. The systems gets stuck there and I can’t do anything. I have try pressing some keys but nothing works. The only thing I can do is to power off the pc and start again.
I also try getting to the UEFI directly from Windows, but it also takes me to that black screen.
Unfortunately, you only have 2 options left:
- Return the system to Acer for maintenance
- Disassemble the system:
- Remove the main battery
- Remove the NVRAM battery,
- “Turn on” the system (I.E. press the power button)
- reassemble the system.
This is not a Manjaro problem but a hardware problem and the reason my current Acer is the first and last system of that brand I’ll ever buy…
I think I will return the system for maintenance.
I don’t disagree with your solution, however I’ve searching the problem and I found this:
Personally, I don’t know if I’m going to try them. I’m afraid of doing something wrong and just make things worse. But anyway, I leave the solutions so people with the same problem can try them.
It seems fast boot and secure boot needs to disabled.
Solution removed. Sorry for not mentioning this as a first, but yes, secure boot needs to be turned off or the Manjaro EFI file needs to be added to your EFI signature list, but that’s a hardware issue, not a Manjaro issue: that’s a first before you install anything other than Windows…
(Monopoly and all that)
You also need to turn off Windows hybrid hibernate in a dual boot.
Hi, I found this another solution:
One of the answers pointed out this link:
In the article, it says:
The GRUB files for the distribution that was installed will be under a folder of the same name as the distribution. For example, if Ubuntu was installed, as in this example, the name of the folder will be ubuntu.
However, in that step I get this: Boot, Microsoft, OEM
There is no Manjaro folder. Is OEM the folder that contains Grub and the one I have to delete? Or I have to follow other steps?
You don’t seem to have a Manjaro problem but an UEFI problem, so can you provide screenshots of your UEFI Boot settings (picture taken from phone is OK).
I was able to solve the problem by resetting the battery with the power button. I’m not going to try again to install linux on this computer though. At least not in the internal drive.
Nowadays, with UEFI that doesn’t protect you any more: settings are stored in NVRAM and the ESP.
Read the UEFI manual that came with the computer. Having 2 ESPs is possible, but even more complex than what you just tried.
P.S. And Acer is particularly
shìte bad with UEFI: twice per year, Windows updates reset my NVRAM to default and I have to rescue my grub… First and last Acer I’ve ever bought!
