Boot Recovery Iso

[Leocricia Castellanos]

Iam doing some custom kernel development with my AGX Orin (Jetpack 5.1/L4T 35.2.1) and inadvertently installed a bad kernel image. After failing to boot the kernel image, the system rebooted itself and is now attempting to do a Recovery Boot instead. From the UART log:

Hi, can you boot properly if the backup kernel is the only system installed?

(At least boot into the console mode so you can modify extlinux.conf.)

Also try if this post helps.

Thank you, that solved the issue! Is there anyway to stop the system from defaulting into the Recovery Boot state? Also, any idea why I am not seeing the prompt to enter UEFI setup? Luckily pressing ESC still opens the setup menu.

It still int this bootmode:L4TLauncher: Attempting Recovery Boot,but the rootfs is ok in the Recovery Boot. I have mounted the rootfs in the bash console of Recovery Boot mode, and the /boot/image of rootfs is also ok.

when in the recovery boot, I mount rootfs and all relevant directory files in rootfs exist. In the extlinux.con, I have config LINUX /boot/Image, the md5sum is right,So rootfs is not damaged. After I made the changes, I restarted and checked again, so it must have been saved

Just got my Librem 15 Pure OS today, I went to turn it on and I inserted the key, created a password and the computer restarted, Now its reading failed default boot. Starting Recovery shell. Not sure what I can do here.

If in the grub menu I choose to boot ubuntu in recovery mode I can press the resume boot option which then always me to boot ubuntu. If anyone knows how to fix this issue it would be greatly appreciated, some things I've tried already are updating the display manager, tried changing nvidia drivers but for some reason it will not let me.

It sounds like you're experiencing some nvidia/display driver issues as you mentioned.9 out of 10 times when this happens it's a bad driver or a corrupt file system.If Ubuntu is not declaring to run in a read-only file system when you booted or when you try to auto-complete commands from the command line for example, then its most likely an Nvidia issue.

Since you have Nvidia and a laptop, I'm going to assume it has an Intel processor.That makes it so that you need to use Nvidia Optimus to switch between the performance and discrete modes of the dedicated GPU. It also means the reason the OS is stuck on a regular boot and not the recovery mode is probably because the recovery mode uses the nouveau drivers (proprietary Intel display drivers)and while they boot more easily, they are also very bad to use, especially when you have an Nvidia card.

if this does not solve the problem, first correctly install nouveau drivers, reboot so you have working graphical user interface like normal, do the steps outlined above (or install the Nvidia drivers with software center, but I recommend terminal, it will actually show what is going wrong during the install and software center does not show you.) that will install Nvidia drivers.after that you can blacklist the nouveau drivers.

Alternatively, you can add Nvidia Xorg server (the Nvidia settings app for Ubuntu) to start with an additional argument so it always boots on performance mode.might be useful if you play games. If not then maybe you could use power saving mode by default.

I have also encountered the same problem and I tried the above ones but maybe due to some reason they didn't work. If that's the case with you then install the Nvidia drivers using terminal in recovery boot window. Below is the steps for installing.

Hello I have an HP probook 450 and I have this quirk where I must choose to boot into recovery mode and then select the first option, I think it reads as boot normally and then I can boot into Zorin. If I select the first boot option in grub I get a blank screen and must hard reboot my PC.

Second, you don't appear to have a discreet GPU in your computer. I believe that your computer may have an integrated GPU, but I find it strange that its not listed either in your screenfetch, and that most certainly is not normal.

These bug reports suggest that the 5.8 kernel May work or the 5.11.0-18 or before may work.

We can test it...

Ensure that in Software & Updates you are set to Main Server. Not a local or regional one.

Ok, to boot into the 5.8 kernel,

Reboot and start tapping the esc key as you pass the Motherboard Manufacturer Splash screen to see the Zorin Grub Recovery menu.

Select Advanced Options for Zorin and arrow key down to the 5,8 kernel to boot.

- For 2 out of the 3 USB sticks i tried (pressing the Backup button in my case), I get a "Booting from external USB" for a few seconds before it goes back to "Booting..." followed by the above error message

That is just REALLY weird that we'd both have the same error at about the same time. I'm in the same boat too - this has been working flawlessly for years. Did you happen to upgrade the firmware recently?

@Fiordhraoi Yes, I did a Firmware update some weeks ago, don't remember exactly when. Usually these are click-and-forget events for me. I run a regular weekly back-up job to my NAS on Wednesday night and as of last Wednesday, everything was still fine.

@StephenB I read the part about the front slot being a shared USB-2 / e-Sata port, but I was assuming this just refered to electrical protocol or something like that. The port certainly does not look like it would fit your regular USB connector. Is one supposed to use some sort of e-Sata -> USB adapter to make use of this port?

I'm currently attempting to find an older USB drive, as the only ones I have around my house are USB3 and it was suggested to me that some of the modern / more complex drives don't register properly. Will update when I can get my hands on one and give it a shot.

@StephenB is that the same mode as using a paper clip to press the reset on the back while powering up? If so, then no, I get the same result of 2 messages showing "Booting" followed by the error message, with no option to select any more in between.

If that doesn't work (sounds like it doesn't), then Netgear can't easily diagnose it - unless there is something they can do from TeamViewer. It's out of warranty, and Netgear doesn't offer servicing. @JohnCM_S or @Marc_V might have some ideas there - if they don't chime in here, you could send them a private message using the envelope link in the top right of the forum page.

While I have found the OS6 native NAS are a bit less particular about the USB devices than legacy ones, USB3 ones will (in my experience) always fail. When you look for a USB2 one, try to get one with an access LED, as that can help you see that the NAS is doing something with it.

Since you read the other thread, I am assuming you already tried the test without any drives and it did not work. If that is not a valid assumption, then you may be premature in assessing the root cause of your failure is the same and has the same fix.

The access LED should do more than just blink during the recovery process. I suspect your drive is being "tested" and found deficient in some way, not really "accessed". Now, the question is whether it's the USB drive itself or something amiss with the recovery software on it.

When holding the reset button, I should be getting some sort of boot menu, from which I could select different options like memory test, disk test, and the one I actually want, OS Reinstall.

That menu does not appear at all. Is there a reason that it is not showing up?

Actually, OS Re-Install is not the same thing as USB recovery. OS Re-install re-installs the OS on the drives from the onboard flash. USB recovery re-writes the onboard flash from what's on the USB. USB recovery does not use the reset button at all. On a 316, it uses the OK button. See this article: How-do-I-use-the-USB-Recovery-Tool-on-my-ReadyNAS-OS-6-storage-system .

I'm helping a friend with his HP CP61-313US notebook computer. Somehow it's not booting from the hard drive. It tries to load Windows and then crashes giving me the black screen where you can choose safe mode, safer networking, etc.

I ordered recovery disks from HP and inserted disc one of the recovery package. It will not boot from the CD. I've gone into the bios options and set the CD drive as the first option. I've done this both from within the F10 bios settings and from the F9 boot order settings. I can hear the CD drive run but it keeps trying to boot from the hard drive.

Is there a way that I can copy this HP recovery disk onto a flash drive myself and try to boot from flash drive. I suppose there is a possibility that the DVD/CD drive is broken. My friend who owns the computer rarely used to drive.

I've determined that the DVD drive on this laptop is either bad or about to fail. I tried creating a Windows repair CD and was able to read the CD. It would give me the "Press any key to boot to CD or DVD" message which I was not getting with the HP factory restore discs. I put the HP factory restore discs in a different computer and tried copying them. I thought perhaps if my drive was about to fail there was something about the factory discs that it would not read but perhaps a copy freshly burned on a blank disk might read. It would almost boot. It would try and then get IO errors on the copied version of the disk. I came to the conclusion I could find other uses for an external DVD USB drive and since they were only $40 I went ahead and bought one. I'm now successfully doing the restore from the original HP recovery disks using the external DV
