Hello everyone, I'm trying to install Windows 10 on an Acer Nitro 5 running Linux. Everything was going well until Windows asked me which partition I want to install it on. Indeed, they are all in "gpt" and Windows doesn't want to install on them even if I format them... So I looked on several forums for a solution, and I finally found that I needed to set the boot to UEFI mode instead of the Legacy mode that I had set, but my problem is that my bootable USB drive (with Windows) is not recognized by my PC when I'm in UEFI mode. I don't know what to do.
Thank you in advance for your help.

Hi,
Wait, let's not get carried away with complicated methods... the Rufus program, which is freeware for Windows, sets up ISOs in GPT mode for UEFI! So you need to remake the bootable USB key using Rufus and in this mode...
Warning: This mode does not appear under Windows XP.

His key might not be in the correct format, it wouldn't start with it...

Yes, because his partitions are in GPT and the ISO will be too with this mode of Rufus; he will have to choose the UEFI boot option from his USB drive at reboot and that's it!!

I was going to say no, but after rereading everything, it’s true that his installation key is the issue.
I didn’t pay attention to the fact that he was working in legacy mode.
Proof that his key is poorly made.

I hadn’t noticed, you said:
"it was necessary to set the boot to UEFI mode instead of Legacy mode which I had set, but my problem is that my bootable USB (with Windows) is not recognized by my PC when I am in UEFI mode"
No legacy, W 10 is a key that boots in UEFI with a GPT partition type for UEFI.
Any tutorial you might have found saying that you need to set legacy mode to install Windows 10 is false and dated several years back.
---------------------------------------
Redo your installation key with this software:
https://download.microsoft.com/download/c/0/b/c0b2b254-54f1-42de-bfe5-82effe499ee0/MediaCreationTool1909.exe
It downloads the ISO and creates the key correctly (create media for another PC and follow the instructions)
Set your BIOS back to UEFI and install.
Don’t change anything regarding the hard disk, with what we have done, it is necessarily in the correct format.
---------------------------------
I’m really wondering how and with what you created it???...
(Rufus we’ll see if needed but it’s only useful in case of doubt about the key created by the Microsoft software that automatically sets the correct format)

Hello,
Here are the steps I would follow
1) get a recent Linux (e.g. >= jessie for debian), so that efi is well supported
2) in the "bios" (uefi), disable secure boot during the installation
3) install Linux normally (without overwriting Windows, on dedicated partitions)
4) reboot into Linux
5) install the package
6) re-enable secure boot
But to be completely honest, secure boot and uefi are among the things that are really not natural for me today (and far too restrictive for the security they provide), so I hope I haven't said anything wrong.
Good luck

Thank you very much, I will try to do it and I will let you know the result!
I just wonder how to reinstall Linux since I unfortunately deleted the most important partition (my PC doesn't go beyond the Acer logo when turning on, then it shows an error message)! Can I do it using another computer like I would for Windows?

Hello,
I'm not quite getting the initial idea...
Do you want to install Windows 10 and Linux on the same PC?
Linux isn't really my "domain," but what's the easiest?
Wouldn't it be simpler to install Windows 10 using Diskpart from the installation USB, since you no longer have Linux, and then reinstall Linux afterwards?
Keep your BIOS in UEFI mode.
Boot from your Windows 10 installation USB.
When you reach the partition table error, press Shift + F10.
A command prompt opens, type and validate each command one by one:
DISKPART
LIST DISK
SELECT DISK number of the relevant disk
CLEAN ALL
CONVERT GPT
At that point, we should be good on the partitioning, so go back, return to the table, refresh or create a new partition.
Choose your partition and install.

Hello,
The initial idea is to only install Windows 10.
Ideally, you should follow this tutorial. In your case, you just need to remove grub and install Windows if it is not already installed.
If Windows is already installed, once grub is removed, you will need to ensure that everything is "as it was" (UEFI, secure boot enabled) for it to be able to boot.
Good luck!
