Error: Unknown Filesystem
Error: Unknown Filesystem
I want to uninstall debian9 on my PC and reinstall Windows. This is not a dual-boot system. I was only running debian9. I deleted both partitions (ext4 & swap) leaving only free space via the installation media after which I plugged the Win10 bootable USB into the port and rebooted the PC. I get the following error:
Press any key to boot from USB.....error: Unknown Filesystem
Rescue Mode:
I understand that I deleted the grub and that it is not reading the USB. I would like to install Windows, but I don't want a dual boot. Additionally, I created a new partition and assigned a FAT32 Filesystem (Via the debian installation media) thinking that it might resolve the issue, but it did not. Thank you in advance for any help. If I posted in the wrong place I'll move the post.
Thanks,
rimuilu

Re: Error: Unknown Filesystem
What PC make/model is it?
How is the HDD connected inside the PC?
How exactly did you delete the partitions?
Did you save the changes?

Re: Error: Unknown Filesystem
Can you confirm that the exact text printed on the screen is "Rescue Mode:", not "grub rescue>" ?
Boot without the USB drive. If the same happens, it means that you were booting from the disk, not the USB drive.

Re: Error: Unknown Filesystem
I am having the same problem with this:
ASUS Gaming Laptop FX73VE-WH71 17.3"
Intel Core i7,8GB
DDR4
1TB HDD
I bought it from this guy at the bus station. But it had some kind of Linux, I think it said Debian. Any way I couldn't install and play any of my games, so I formatted it with a Dos boot, repair usb stick. So anyway now I am trying to install Windows 10, but it says the same thing:
Unknown Filesystem, and it can not install. I hope this Linux did not brick the Laptop, but it seems like it did, How can I install Windows 10 to my laptop ?

Re: Error: Unknown Filesystem
What I would do is boot from a live CD that has GParted. Then I would use GParted to create two primary partitions and format them as FAT32. The first partition I would make 500 MB in size. For the second partition I would use the remainder of the disk space.
Optional (but desirable): Create a third partition and use it as a backup/data partition. This is only feasible if the HDD is fairly large, such as 200 GB or more.
After booting with the Windows 10 installation media, I believe that you will be able to select those partitions that you created and format them as NTFS. I would do that because the installer may refuse to install Windows if you don't.
NOTE: If there is an EFI partition, leave it alone unless you are absolutely sure that you know what you are doing.

I tried to reboot with the pen drive in just to be sure. This is what comes up when I restart the PC with the windows pen drive plugged in:
Press key to boot from USB.....error: unknown filesystem.
Rescue mode...
The second is what comes up if I just power on the PC.
Unknown filesystem.
Rescue mode...
If I plug in the pen drive that has debian installed, I have no problem installing debian.

The debian that I have does not have a live option. It's a simple install from boot. I can install Mint or Ubuntu and use the live option to install gparted and try that. Would that work just as well?
Re: Error: Unknown Filesystem
The PC is Dell Optiplex 780. Bought it second hand and then cannibalized other PCs for parts. It is connected via SATA. I didn't save anything as there was nothing to save. I was just messing around with it because I don't know much about Linux. I deleted the partitions via the debian graphical install. I went through all the initial install steps then chose to use the entire disk for partition. When it showed that I had an ext4 and a swap I selected each partition and then selected delete which then gave me all free space. My thought was that now having free space I would be able to plug in the Windows drive and boot from it without issue and windows would create the needed partitions. An obvious fail.1byte wrote:What PC make/model is it?

Re: Error: Unknown Filesystem
First check that your USB with Windows on it is ok. Do this by plugging in to another computer and booting from the USB. If it starts ok then no need to proceed with the installation, but, if it doesn't then you'll need another USB with Windows on it.
If the USB started ok in the other computer then boot the problem machine with a Live disk and use GParted to create a new partition table on your HDD. No need to create partitions - Windows can do that as it needs. Then reboot with your Windows USB and proceed with the installation.

Re: Error: Unknown Filesystem
If you get the following :
This is from the part of GRUB (default Debian bootloader) remaining on the hard disk after you deleted the partitions.
If you get the same messages with and without the Windows USB drive, then the PC is not booting from the USB drive. Something may be wrong with it. As already asked, did you test it with another PC ?
Anyway, the inability to start the Windows installer has nothing to do with the former Debian installation. It is not a Debian problem.
Now about the prompt
This is not from GRUB. It may be either from the BIOS or the USB drive. It reminds me of a similar prompt displayed when booting from a Windows installation CD or DVD (never installed Windows from a USB drive).
Do you also get the prompt when booting from the Debian USB drive ? If yes, it is from the BIOS. If no, it is from the Windows USB drive, which means that somehow the BIOS manages to boot from it.
Do you press any key when prompted to do so ?
Code: Select all
error: Unknown Filesystem
Entering rescue mode...
grub rescue>

Re: Error: Unknown Filesystem
Thank you all for your help. I ended up creating a new partition table and then created new partitions of the needed sizes which left free space. From there I installed Windows. How can I mark this as solved?
