Airboot no longer works...

Hi All

An interesting evening so far. Thought I would create an ArcaOS 5.0.4 USB Flash Drive install which worked OK; booted fine to the Maintenance Console so I would expect to be able to install from it.

However, on rebooting from the Maintenance Console Airboot threw a wobbly and delivered this message:-

Scanning...
- Your system has at least one broken partition table entry or your hard drive contains bad sectors. System halted.(HDD2)


Hmmm... does not look good.

I booted from an ArcaOS5.0.1 dvd to the Maintenance Console and from there discovered that there does not seem to be any Airboot docs installed on my ArcaOS 5.0.1 system.

I did locate airboot2.exe in \sys\bin and ran it thinking to delete the Airboot installation and then reinstall. So I then discovered it is a case of using "lvm:newmbr:1" on the command line to remove Airboot.

Before going any further I chkdsk'd drives with no reported problems, no problems at all running dir on any drive.

I had a look at the disks/drives using LVM - which made no complaint about bad partition table(s).

As I have DFSee installed I fired that up - I would like to say no problems reported but there are some lines that have me puzzled:-

At least 4 non-trivial minor warnings were not shown. Use 'part -w:t -t-' for details.

DFSee OS/2   15.0 : Executing: part -w:t -t-
Command timestamp : Monday 2020-05-11 19:29:39
 Pid02=J: warning : Logical partition is marked as startable! (active)
 Pid03=H: warning : Logical partition is marked as startable! (active)
 Pid04=L: warning : Logical partition is marked as startable! (active)
 Pid06=D: warning : Logical partition is marked as startable! (active)


Not sure how they have become marked as startable, H: and L: are boot drives and on the Airboot menu but J: and D: are not - and I do not think logical drives can be marked startable.

Is this what Airboot was moaning about?

Having checked that my ArcaOS5.0.1 installation was Startable I rebooted and had no problem booting my ArcaOS installation.

I tried reinstalling Airboot which worked fine but on reboot delivered the above "- Your system has at least one broken partition table entry ..." After again booting the dvd to Maintenance Console and removing Airboot I can at least boot ArcaOS.

I can only guess that something is wrong with the Airboot configuration as there does not seem to be anything wrong with partitions or filesystems in use.

The problem is: How to get rid of the existing Airboot configuration?

Any "cures" out there?


Regards

Pete




Roderick Klein:
Simple, boot from the latest ArcaOS DVD you have. Via the management console, start minilvm. Delete airbooot and reinstall. I think that should resolve the issue.

Pete:
Hi Roderick

Why you think that will work I have no idea - I have already established that removing Airboot then reinstalling does not lead to a working system.

However, I have not used miniLVM so I gave it a try. No, that does not work.

Either there is a problem with the drives that is not reported by LVM or DFSee or there is now something wrong with Airtboot which had been working fine for years prior to booting the ArcaOS 5.0.4 USB Flash Drive.

Possibly the non-removable Airboot configuration is the cause; anyone know how to remove that?

Dave Yeo:
Is it possible you've changed the boot order in the BIOS? I think you can use DFSee to replace the MBR which should remove the Airboot configuration.

Pete:
Hi Dave

You are an accidental genius  ;-)

No, I had not changed the boot order in the BIOS *but* I had enabled USB boot support in order to boot the ArcaoS5.0.4 USB flash drive.

That in turn enabled boot support for my *internal* USB multi card reader and added the device to the boot list.

My guess is that Airboot flipped out when presented with a mass of empty usb drives (4 slot reader, lots of card types supported).

Having turned off usb boot support in the BIOS and reinstalled Airboot all is now working as it should.

Thank you for the BIOS prompt  :-)


No, using either lvm or dfsee to replace mbr does not remove the Airboot configuration, it only removes Airboot code. I was thinking about asking Jan (DFSee) about that problem but no need now  :-)

Pete
