I did try the same experience this evening with the 64 bit version for AMD.

different from the 32 bit version, with it the installation with the GNUinOS installer did work immediately (and the other way I did use in 32 bit starting from the iso live and installing after the installation from refractainstaller out the live started image would not start).

the result is about the same.

but the problems begin after that trying to start the new version as regular snapshot-ISO from the full installed version from Hard Disk (the normal correct way to do that!): it seems impossible to get keyboard or accede to x from usb card. GNUinISO seems to have a special start modus giving on my PC (it is "transformer" Dell Latitude PC with touch screen and keyboard and touch pad and joystick-pin in the middle of the keyboard between G and H) only disturb. As for the 32 bit Snapshot, the new size is 1 GB (probably 10 % more probably because of the full installation) but the snapshot is not usable (I did try to interchange the display manager from LXDM (why lxdm? it is in the last time unusual) to slim adding JWM to avoid the possible problem of xfce4 having to work with some part of lxde but it is not better: In ram only start of the snapshot iso image, x appears but no keyboard or touch screen reaction (the mouse works! it is possible to start app's!)...
sorry...

burn he new iso is no problem: if the usb-card did already have some refractasnapshot ISO do nothing else as reuse directly after the snapshot is finish:

open thunar, hit on the 3d icon at the top and you see directly /home/snapshot . Hit on snapshot and mark the iso file. right mouse key, select copy then

# dd if=/home/snapshot/(right mouse key, select paste) of=/dev/sdb status=progress

that happens fast as the iso is so tiny!

if the usb card didn't contain such an iso image of a os, prepare it so:

- open gparted to format the card (you can check and see in gparted if sdb is right in your case! It can varie)
- for that iso (until ab. a little less than 2 Gb in case of other ISO's) format it in: vfat16 ! Yes 16 not 32! (only in case of bigger ISO's  select vfat32...)
- mark bootflag (in gparted!) it is important
- unmount /dev/sdb

and continue with dd !

Notes for the precedent message:

(*1 as far as know is luakit COMPLETELY free an non commercial as well as open source, over that one of the actual browsers also in 32bits, extensible.

(*2 info is less known as man but offers where present really more

(*3 didiwiki is the most small text processing system I know, works in pure console mode in each pure console mode browser and in graphic browsers can manage some picture in the text! The result is saved in a pure text document (hidden in the hidden sub dir named .didiwiki) excepted, of course, the pictures... It proceed different sizes of title, sheets, graphic mode normal, italic, underlined and sizes small, normal and big, and can open external links! Look at the installed size! Didiwiki HAS TO BE in each installation... The help is integrated and is a good documentation also for people with difficulties with English! After the installation, invoque in the url bar localhost:8000 (in luakit type "o" and enter localhost:8000)

(*4 magicpoint is a very small «presentation's software» to start and use from the commando line. it is the unique (as far I know) linux application usable with only 3 modules of Cygwin (being easy to simply copy) in Windows since Windows 95! For people having really rarely to present somewhat (for ex. themself) often enough! In baslin (Basic linux, the graphic Linux for only 2 FD floppy's, the ISO file version continues to be present in the web, but not the excellent Linux training based on it for windowers coming to Linux, balin can be started also directly out the old DOS file system) mgp was one oft the only two graphic applications
but did contain a supplementary function: it was able to support hand drawing with the mouse!

(*5 mhwaveedit = the minimal but about perfect sound processing system

(*6 mplayer: for those using videos to learn somewhat, the old mplayer allows to start exactly at the point of video where you will see a detail detail to learn. See the man page! No problem... To repeat tomorrow the same viewing to learn and learn again, see your hidden file /~/.bash_history! You can copy those files for ex. in a (not hidden) file for ex. ~/sportAshtanga-yogaPattahbiJois002 or transmit then to someone or copy on a different Pc as the times are in real time and don't vary from PC to PC...

(*7 ocr: there are different ocr's in Linux. Tesseract-OCR is probably the good one.

(*8 my lines in /etc/ftab:
/dev/sda5    none    swap    sw    0    0
/dev/sda6    /home/.../0    ext4    defaults    0    2
(as I have different PCs, 6, partially very old and transmit by my dead father, I can't replace then through a modern PC, I continue to use the old hard disk organisation in a logical partition, non important witch one. Sda5 is always swap, sda6 is always data bis about 1 TB in ext. 2 so that also Puppy linux Angel Pup with the emulation of a lot of old computer like Commodore, Sinclair etc. can process the files, and since I do that, never some problem with my data! If only for data, ext2 continues to be the best system! Sda7 is the android86 if present, and sda8, sda9 etc. the full installations...)

Thank you very much but pls look at the date of parution: 7 Mar 2023!

thank you very much. Save and recopy OPEN data is no problem. The problem are the hidden data possibly in divers repertories as /etc , /usr/share and, of course, /home/jef . For ex. I did not find some content for certain app's in /home/jef/.config/somewhat/... . The subdir's somewhat exist but are empty. What is the recommended approach to back up the own personal data just bevor doing refractasnapshot alt. the actualization of the entire system, some kind also of refractasnapshot restricted of the usual and typical own personal data (/etc/alternatives , /etc/grub.d , /usr/share/some_growing_subdir's , /var/some_growing_subdir's possibly containing kind of user' s data, and of course hidden data in /home/jef/ like /home/jef/.config , /home/jef/.mozilla for those using mozilla, etc. if other typical other subdir's contain usually data changed yesterday (I don't speak from very special needs for those installing very special software: they are aware about that, I hope)? Are changes recommended in the settings of the common refractasnapshot? Can then the refractasnapshot be used for that second wave for the own data with other adapted / also special settings to save the own user's data immediately before I start with an important system actualization where I can not appreciate in which condition my system will be after that. Refractasnapshot is so fast and secure, it would be a great tool for that. My OPEN data are all (including /home/jef/Downloads through a link instead of the subdir ~/Download itself in a separate partition mounted in /home/stef/0 through /etc/fstab by start so that I have nothing else to do at actualization time as umount /home/stef/0. They come so never into the snapshot (and would not be possible: the partition is about 1 TB big!)
