Are these USB3? Essentially, installing a Linux system to them is more intense than just copying files, even large files. There's an amount of indexing, finding files and so on that isn't there in copying say, a DVD sized image across. There's a subtle difference between a cheap 16G USB stick and one of the large high capacity USB sticks from a major manufacturer that might cost ten times as much. Also, USB connected devices are different: I'd feel happier, for example, installing Debian to an SSD in a good caddy connected via a short USB3 cable I trust :) > Semih Ozlem <semihozlemlinuxuser@gmail.com>, 27 Şub 2021 Cmt, 15:19 > tarihinde şunu yazdı: > > > Should I then be suspicious of a possible attack on the system in case the > > system fails, if both debian and ubuntu are fairly stable?

Before I did that: I'd use Windows tools to list everything possible about the system and write it down on a piece of paper - including whether it's booting from UEFI, what the video information is, disk size and so on. I'd also boot the machine from a piece of Debian live media - check lsusb, lspci, any dmesg messages about missing firmware - again, write it down. Use the tools from Microsoft to get hold of a copy of the latest Windows install media and use those tools to write it to a USB stick. Keep that somewhere in case you _ever_ need to reinstall Windows :) Then check back into the list and I'll talk you through installation if you wish. One thing that is important: always resize disks first with Windows tools before installing any other OS. > >> > The third reason is I simply do not > >> > at the moment have the time to backup the existing hard drive before > >> > installing a new operating system on it, and also that should it > >> > become unusable or stop functioning (I had debian installed on a usb > >> > 64 gb of size that stopped booting).. > >> > >> Ah, USB sticks *do* stop working or lose bits without warning.

Accept that it might be ten items long - then accept that it might take a while to do the first thing on the list which is to install Debian :) If you've installed Ubuntu a few times, the Debian install is not unfamiliar. If you've only ever used the graphical installer, I would suggest that you choose the expert option (under Advanced options) because this will ask _all_ the questions. If your Windows machine functionality is business critical/vital to your life, I'd suggest practising the install a couple of times on a spare machine if you can get one rather than destroying everything accidentally and blaming the list for telling you to do it :) All the very best, as ever, Andy C.

Grub writes a bootloader to the MBR of a normal drive, but a USB stick may not have a partition structure, in which case the bootloader will be written to the start of the drive. If this gets damaged, you can use a low-level disc utility to copy it out and check it, but the easier way is to boot from a rescue USB stick, then try to chroot into the faulty OS and update grub from there, which will rewrite the bootloader. The recovery mode is grub itself plus a number of utilities and drivers. From here, you can generally find drives and partitions, mount partitions and edit files if you can see what's wrong. It sounds like the early booting part of grub is itself damaged in your case. And no, LVM snapshots are nothing to do with boot or recovery processes, they are a means of freezing the files of an installed operating system so that a proper backup can be made while still allowing the system to run. Changes to files are stored in a buffer area, and read from there, then when the backup is finished the snapshot can be closed and the file changes will be merged back to the real file locations. The system will obviously run more slowly while the snapshot is open, but that may be far better than shutting it down for an offline backup. If you try to make an online backup without using this method, some files will change during the backup, meaning that the set of files that are written to the backup may not be consistent enough to run properly as a complete system. Certainly database daemons must be stopped, as well as anything else outside the core OS that makes persistent changes to files (e.g. a mail server). Most changing files are temporary, so it is often possible to get away with an online backup without a snapshot, particularly if you only ever need to restore single files or directories. Cloning a full working OS is generally best done offline, unless you have LVM plus space for the buffer. -- Joe

The only thing that worked was the power pass-through to the monitor. No fans, no lights. But as the PSU is 21 years old, it's no surprise really. Or did your POST work, but then they did nothing after that? Or perhaps they said there was no operation system? All these faults, so far, have nothing to do with CENTOS or Ubuntu, which haven't even started to be loaded yet. > > OK, that simply should not happen.

Hmm, I would treat anything copied off those sticks as suspect, not because of any sort of attack, but just corruption by the stick. > But > when I try to boot from 64 gb usb flash disks (one with ubuntu 18 04 the > other debian 10 point something installed on them) the boot process does > not complete and the login screen does not appear. I wouldn't have the patience to wait for a graphical login. A console login and startx might be preferable, so that you get faster feedback on whether booting is working. Add "systemd.show_status=true" to the kernel line is grub.cfg too. > The two recovery modes > (I guess those are the snapshots no?) do not finish booting either. I'm not sure why *two* recovery modes, but a freshly installed system typically has one kernel: recovery mode is just the kernel parameter "single". (You might have two if you installed from out-of-date media, leading to an immediate upgrade during installation.) Anyway, USB sticks. Last week I installed buster onto an 8GB stick to evaluate a laptop with windows on it. The installation went fine, and the next day I booted it up to install a load more packages onto it. Apt-get kept complaining about files with no newline at the end, so I closed down, and mounted the stick on my desktop. Several of the meant-to-be-text files in /var/lib/dpkg/info/ were just binary garbage. Later, I thought I'd look for any errors reported during installation in the installer's syslog, but the stick now wouldn't even mount: the partition table was corrupt, so I had to copy the GPT backup table onto the main table with gdisk. This evening I tried to boot an old laptop with the official buster installer on a stick. I couldn't get the BIOS to see the stick (in order to promote it above the hard drive in boot order). I tried booting using another stick for doing the promotion, and then swapping to the real one, but that just complained of "no operating system". So then I had the bright idea of plugging in a 10-year old Trust hub (£8 at Asda), and putting the stick in that, and, sure enough, it booted up. So persistence pays. Cheers, David.

Regarding the following, written by "Semih Ozlem" on 2021-02-26 at 08:54 Uhr +0300:
>lvs is in which package?
If it's not installed on your system (the package being `lvm2`),
then my suggested fix won't work for you anyway, since your system
isn't set up to use Logical Volume Management.
