[04:27] hey [18:35] I have been attempting to install Jammy Jellyfish on my HP Pro laptop, using a USB drive, but was getting error messages when I rebooted after the "installation complete" message. After that happened I was able to try it out without installing and had no problems for a couple of days. Then Firefox crashed and could not be reopened. When I rebooted [18:35] I got the following message: "ZSTD Compressed data is corrupted - System halted". I am wondering whether this indicates a problem now in the USB drive or if it is rather in the laptop itself.  Tomreyn kindly gave me some help a while back ( before I had a nick) which enabled me to eliminate one original error message I was getting (re VMX). Any [18:35] advice would be appreciated. [20:06] willh: so you installed to your internal disk? is this a hdd, an ssd, or something else? [20:25] to hdd from bootable flash drive. [20:27] willh: are you able to boot from the hdd now? [20:27] like, does it work sometimes or have you found a workaround? [20:28] does this happen to be you? https://forums.linuxmint.com/viewtopic.php?t=395876 [20:28] it's the only occasion that i can find of the message you reported you see at boot [20:30] hmm, you seem to be in canada, not florida, and have a different name, so probably not. [20:30] this person also uses hp hardware, though [20:32] Cannot boot, have no workaround.  I had read that post at that link. I am in Canada, as you say. [20:36] That fellow in Florida clearly has higher level of technical knowledge than I do. [20:42] I was thinking that maybe I should create a fresh bootable USB drive and try again with it. [20:44] willh, it looks like your HDD is dying. [20:50] So Diogenes, you mean that the ZSTD compressed data is corrupt message relates to the HDD, not the flash drive? [20:52] willh, TLDR, i don't understand what is has to do with the USB drive, it is only used for installing the system, if it gives an error during the installation, in 90% of cases it's a faulty USB drive, in rest, it's HDD. [20:55] OK [22:07] willh: you can try to boot to grub and then select an older kernel from the "Advanced" menu, this may let you boot [22:07] you can also try just booting the default kernel from the grub menu manually, sometimes this also helps. [22:09] if you can get the system to boot, you can check system logs with journalctl -f (which will print new log records as they are being logged) OR journalctl -b (which will show any logs since last boot) [22:12] if you suspect that the hdd may be defective, you should look for "media sense" errors on journalctl [22:31] Thanks a lot Tomreyn, I will try these. Before the most recent attempt to install Jammy,  I ran an expansive test of the hard drive, and it passed, 100%. I was previously running Mint, by the way. [22:32] good luck! [22:33] Thanks again.
