Re: Error when booting: Diskfilter writes not supported - kpanic - 06-18-2018
[member=5916]trinidad[/member] , well I have probably missed that part when he mentioned something about Windows.
And it really does not matter unless he is running a really strange hardware.
But I don't think this is the case since the HD is under 200Gb.
It would be nice to get his Linux up and working. I hope the 'dd' will
do the job - but as this is really an exceptional case, I would not bet on it
Nothing to do with Windows, BIOS or MBR. This problem has to do with some process locking access to the
hard drive and since /dev/sda1 already seems to have an LVM signature - probably from some previous installation - I guess
one possibility is that LVM still sees that partition belonging to it. That is why I want to wipe out the contents
including the meta-data from that partition.
Let us see

[member=7701]kpanic[/member] ... with your suggestions, I think I got through the partitioning process. I'm now installing, and got to the hard drive options, and I chose "something else." Is this what the screen should look like?

When you say: tell it to mount sda1 to / do I need to do anything here? Or is it ready for me to click Install Now?

All the advice you have given so far is thoughtful and accurate. I'm only guessing that he is on a machine with 32bit BIOS. If the memory is 2gig and the HDD small that can often be the case. It was common on such lower end hardware for there to be BIOS persistent RAM that expected a 32bit partition. Usually POST will report an addressing error when booting on such machines, and Debian will report a 32bit address breaking warning. Most of these low end BIOS allow F1 to continue booting after the POST warning if you can get the system installed. The other workaround is that dual booting usually works ok on these machines but in order to remove Windows afterwards you must first de-fragment & shrink the Windows partition, then copy it to a new partition, then format the old partition to ext4 and install Linux there, then remove Windows and add the partition space onto the new Linux partition after Linux is up and running. None of these low end BIOS machines came with a Windows installation disk. Imagine that. Your input since joining the forum has been excellent.

[member=5916]trinidad[/member] [member=7701]kpanic[/member] Thank you again for helping me with this.
It is an old laptop, that long ago ran WinXP. Before LL4.0, I had it set up to dual-boot Linux Mint and Linux Lite 3.x. I decided to dedicate it entirely to LL4.0, and after test-running on a live USB drive, I told the installer to replace everything. It seemed to work fine, except the Grub boot error message, which I could bypass with just a few seconds delay.
I'm looking at the BIOS screen. I don't see anything about it being 32-bit specific. Is there something I should look for?

[member=5916]trinidad[/member] , ok, thank you for helping out!

[member=5059]whateverthing[/member] ,
Great, that picture looks exactly like it should be. Hopefully you got though the
installation!
Re: Error when booting: Diskfilter writes not supported - whateverthing - 06-20-2018
Haven't finished installing yet. Was waiting to make sure it looked right.
But when I click "Install Now," it says: No Root file system is defined. Please correct this from the partitioning menu.
In that installation partition list, when I double-click /def/sda1, the pop-up says:
Use as: do not use this partition
Should I change that to one of the other options in the drop list? There's Ext4, Ext3, FAT16, FAT32, and several others. Or is there some other way I need to tell it to use it as root?
Re: Error when booting: Diskfilter writes not supported - kpanic - 06-20-2018
[member=5059]whateverthing[/member] , oh yes!
Please, edit the partition /dev/sda1 and choose it to be ext4 and ALSO choose it to mount to /
Re: Error when booting: Diskfilter writes not supported - whateverthing - 06-20-2018
[member=7701]kpanic[/member] That seemed to work. I completed installation this morning (my time), and on first reboot I didn't see any Grub error messages. I'll need to spend more time with it this evening, and I'll remove the virtual box support to speed boot time. I'll let you know how it goes!

[member=5059]whateverthing[/member] , that's good news, congratulations!
