Error 1962: No operating system found

#1 Post by Silvergator »

When trying to boot from HDD (sda) I get: “Error 1962: No operating system found”. The computer originally had Windows 7 installed. I installed Sid weekly build and instructed installer to use the entire disk.

I’ve followed all the suggestions I’ve found using Google including using reinstalling from Debian installer, grub-install, and Rescatux. There's 390 matches on this form to "no OS found" so I'm asking for help to narrow the search. My system will only boot from USB or SD card. Supergrub2 indicates choice of /boot/vmlinuz-6.00-4-amd64 (on hd1,gpt2, the SD card). Thanks in advance to anyone who can point me in the right direction. I know that there is a fundamental principle about boot that I'm completely missing. Probably because the installer has always solved the issue in the past so this is the first time I ever had this problem in over 10 years of using Linux.

After booting using supergrub2 on SDHC memory card (sdb) my system is as follows:

Please reformat your post. Do not put normal text with overly long lines within code tags.

Terminal text output should be within code tags, not preformatted text tags. I didn't see the post before p.H commented so assume you have edited since. neofetch shouldn't be posted at all on the forums IMO, inxi is much tidier and can show more useful information.

p.H is the boot expert around here so I'll pass on trying to diagnose your issue.

Looks like you installed for EFI boot. Check https://wiki.debian.org/UEFI#Force_grub ... media_path

Thanks for responding, however I am not fully understanding your response.
1. Was installing for EFI boot the correct operation? The Linux filesystem seems to be properly installed on the HDD (sda2) and everything works as expected once booted using supergrub1 on a sdhc card.
2. I think that when I did the forced installation, the installer wrote to my sdhc card (sdb) and not to my HDD (sda). I had to reload supergrub2 to the sdhc card. Is there a way to force the installer to use the HDD rather than the sdhc card for boot installation?
3. In fdisk, I see a Boot column with an * for /dev/sdb1 but no Boot column or * for /dev/sda1. Is this meaningful?
4. Can I manually copy files to the ESP on sda1 to fix the problem? Below is a view of my /etc/fstab file:

Code: Select all

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# systemd generates mount units based on this file, see systemd.mount(5).
# Please run 'systemctl daemon-reload' after making changes here.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda2 during installation
UUID=70137697-6171-4975-9585-e68ebecd5d11 /               ext4    errors=remount-ro 0       1
# /boot/efi was on /dev/sda1 during installation
UUID=1E69-139E  /boot/efi       vfat    umask=0077      0       1
# swap was on /dev/sda3 during installation
UUID=2d834e5c-177c-4f17-9e60-596ff831ec11 none            swap    sw              0       0
/dev/sr0        /media/cdrom0   udf,iso9660 user,noauto     0       0
# QNAP NAS
192.168.1.200:/	/home/QNAP/	nfs	rw,auto	0	0
Note that sda1 is mounted at /boot/efi but does fstab even get read during boot?

Thanks,
Bill

Do what p.H linked to in the wiki.

Code: Select all

dpkg-reconfigure grub-efi-amd64
and select "Yes" at the step to "Force extra installation to the EFI removable path".

I would try simple

Code: Select all

grub-install && update-grub
first, and do the above if that's unsuccessful.

I have done the dpkg-reconfigure and grub-install in the past but I just repeated the suggested commands again with no apparent change in the boot behavior. I'm going to try resetting the bios to the default settings to see if the message is from the bios from the original Windows 7 installation.

The platform firmware supports it, so yes. You may have better luck with legacy boot if the firmware supports it too.

Highly unlikely, according to the posted information. What do you mean by "forced installation" ?
Silvergator wrote: 2022-12-06 19:07 Is there a way to force the installer to use the HDD rather than the sdhc card for boot installation?
Of course. Remove the SD card before installation.
Silvergator wrote: 2022-12-06 19:07 3. In fdisk, I see a Boot column with an * for /dev/sdb1 but no Boot column or * for /dev/sda1. Is this meaningful?
Not for GPT nor EFI boot.
Silvergator wrote: 2022-12-06 19:07 4. Can I manually copy files to the ESP on sda1 to fix the problem?
It depends where the problem lies. Can you install boot-info-script, run bootinfoscript and post the report ?
Silvergator wrote: 2022-12-06 21:23 Note that sda1 is mounted at /boot/efi but does fstab even get read during boot?
Of course it is. How else would sda1 be mounted ?

Re: Error 1962: No operating system found

#9 Post by Silvergator »

Thanks for the detailed answers.
Items:
1. The bios has no EFI/legacy selection option.
2. This is what I mean by forced: Image
3. Unfortunately, the sdhc card contains the install Debian program. I don't see an alternative.
4. Will do. This is new to me and I'll run and report.
I have no idea how sda1 is mounted at boot.

Computer booted using supergrub2 on sdhc card (sdb). Debian filesystem on HDD (sda).
Here's the RESULTS.txt file from sudo bootinfoscript:

"Removable media path" is a misnomer. It has nothing to do with removable media such as SD cards.
The report does not list /boot/efi/efi/BOOT/bootx64.efi. Is it present ?
Did you check the UEFI boot menu contains a "debian" entry ?

Silvergator.What is the "Removable media path" ? The wiki page on EFI indicates that it's "(e.g. \EFI\boot\bootx64.efi for amd64/X64 systems)". I don't have this path or a bootx64.efi file. Note: sda1 is mounted at /boot/efi.

Silvergator. No. But there is a /boot/efi/EFI/BOOT/ but bootx64.efi is missing. (Is bootx64.efi required if shimx64.efi exists?)

The entry is there but the path shows backslashes (dos). Is this significant?

I thought I'd try renaming (moving) or copying /boot/efi/EFI/ to /boot/efi/eif/ but I get the message that the file exists. What am I doing wrong? I'm trying to create the removable media path from the ESP wiki.

Code: Select all

root@debian:/boot/efi# mkdir /boot/efi/efi
mkdir: cannot create directory ‘/boot/efi/efi’: File exists
root@debian:/boot/efi# ls -al

ls output with relative paths is ambiguous. Please post the output of:

Code: Select all

find /boot/efi
Note : FAT is case-insensitive.

No, I mean the UEFI boot menu displayed on the screen at boot time or in UEFI boot settings.

/boot/efi/EFI/BOOT/BOOTX64.EFI is present. Along with a lot of garbage, possibly caused by "repair" attempts.
The EFI partition should contain only these files installed by "grub-install --force-extra-removable" :

Code: Select all

/boot/efi/EFI/debian/shimx64.efi
/boot/efi/EFI/debian/grubx64.efi
/boot/efi/EFI/debian/mmx64.efi
/boot/efi/EFI/debian/fbx64.efi
/boot/efi/EFI/debian/BOOTX64.CSV
/boot/efi/EFI/debian/grub.cfg
/boot/efi/EFI/BOOT/BOOTX64.EFI
/boot/efi/EFI/BOOT/grubx64.efi
/boot/efi/EFI/BOOT/fbx64.efi

"Error 1962: No operating system found" is a BIOS/UEFI message. I recall when I first used my current system ~6 years ago, I had to change a setting in UEFI setup from something like "Windows OS" to "Other OS" before I could get it to work with Linux. I don't remember exactly the setting, but worth a look.

These images show the GRUB menu, not the BIOS/UEFI boot menu or settings.
