That's probably irrelevant: flash drives can and do fail with the occasional missing write under heavy load. 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 <semihozlemlinuxu...@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.
