troubles copying installation files - dd can't find dev

Hi,

I want to upgrade from Helium to Boron. I made an attempt to make a bootable flash drive. But it failed multiple times for different reasons. My main question at this point is why dd can't write to exfat? Flash drive (4MB) is old. So is my netbook (eeepc 1000 asus). Way down below in the command line I changed 'bs=16M' (as per Debian instructions) to bs=4M because the old flash drive is just 4MB. What should I do?

Re: troubles copying installation files - dd can't find dev

I forgot to type the preceding slash > /dev/sdc1
Now dd is copying -)

Re: troubles copying installation files - dd can't find dev

Unfortunately no files got written to the flash drive. After ejecting flash drive does not automount anymore.
I still have a problem.

Re: troubles copying installation files - dd can't find dev

why dd can't write to exfat?

Go ahead and format it fat32; dd destroys that anyway.

sudo dd if=boron-1-240124-i386.hybrid.iso of=dev/sdc1 bs=4M status=progress oflag=sync

Don't use the partition number  "of=/dev/sdc"

Re: troubles copying installation files - dd can't find dev

I changed to another pendrive named SanDisk_16G. Still no luck.

dd command is destroying vfat file format as well. No data are written to SanDisk. What should I do?

Re: troubles copying installation files - dd can't find dev

This what dd does. It totally rewrites the USB drive. It is correct the output of lsblk -f

Did you set the computer to boot from USB (in BIOS) and try to boot it? It should work. I once had an old eeepc 7 inch and it worked, that was a long time ago.

You should be able to reformat the usb drive later on after you have successfully installed boron with gparted

Re: troubles copying installation files - dd can't find dev

Current boot priority in BIOS show:
[Removable Dev.]
[HDD]
[CD-ROM]

In the right pane it says that a device enclosed in parenthesis has been diabeled. So it looks all three devices have been disabeled, which cannot be true since startup uses HDD every time. This doesn't make sense. I assume USB pen drive will get recognized as Removable Dev.

Also flash drive SanDisk_16G contains no data after dd-ing. Dd says it is copying all data to /dev/sdb but no confirmation of writing data to disk. Indeed no data got written to SanDisk.

I did figure out why file manager lists two flash drives when inserting one pen drive. The other drive is a multi flash reader sitting flush within the casing of the Asus netbook. I did not notice that at first. I haven't been using the netbook after Helium got released.

Re: troubles copying installation files - dd can't find dev

I found some new information. https://support.siliconmechanics.com/po … e-using-dd. My process does not end with a single 0 on the last line. Which means data does not get written to disk.

As per other tips from the internet I umounted the flash drive before dd-ing Boron onto it. No luck with that either.

In /var/log/messges I tried to actively monitor what happens during dd-ing. The pen drive connecting gets properly recorded. But nothing about dd process.

Re: troubles copying installation files - dd can't find dev

I used the cp command this time to write to /dev/sdc. Does it look like the installation files are all there?
Device sdb is a multi flash reader 128GB (micro sd). Strangely 100% use with only 1.3G data on it.
Device sdc is a pen drive 4GB (which was my target drive this time).
