Strange, when I updated to a 1TB drive, Bootmanager stopped working, or actually only showed my smaller drive, and I was informed it didn't work with drives over 512GB or so, so I switched to airboot.

Hi Dave,
I think that 512GB limit is the maximum size if the OS boot partition.  It works for me on my standby computer with a 1TB and 2 2TB drives that have OS/2 WsEB, ArcaOS and a Warp 4 maintenance partition spread out over all the drives.  Actual boot partitions are 2GB.  ArcaOS was the frustrating install because it wants the boot partition to be a primary one whereas with all my OS/2 installs they have been on extended partitions.

I think you let some other OS make some, or all, of your partitions. If you wipe a large disk (use the ArcaOS tool) and make all of the required partitions (including windows, and Linux) with (mini)LVM, then format the boot volumes as JFS, you won't have those problems (unless the other OS messes with what you did). Don't forget that that will delete all of the data on the disk, so be prepared with GOOD backups.

VERY IMPORTANT: Do not, ever, let anything else mess with the disk setup. That is pretty well guaranteed to cause problems.

I have a couple of 1 TB disks with win10, a couple of ArcaOS boot volumes, a FAT32 volume, and a couple of other OS/2 volumes. They all work, as expected (including a boot volume at the end of the disk).

Boot manager probably has problems with large disks, but I have not, yet, seen Air Boot fail with one (probably could happen if the BIOS is not up to the job). I do have one ancient DELL, where Air Boot refuses to work, but I am sure that is a BIOS problem, because I can put the same disk into a newer machine, and Air Boot works.

My boot partitions are usually about 2GB, occasionally 4GB. The problem was none of the drives on the 1TB disk showed up in BM and when I asked about it, the story was that BM didn't support such large drives.
All my ArcaOS installs, and I have a few, are on logical partitions. Weird that you had problems.

Hi All

No problem installing to 1Tb disk *after* using DFSee to prepare the disk by wiping start of disk to 0(s). I seem to recall LVM cannot see the full 1Tb - only sees 512Gb - without performing this action first. After the disk is "prepared" partitons/volumes can be created using either LVM, miniLVM or DFSee

No problems installing ArcaOS to Logical volumes here although I was selecting to install to drives that had already been created and had previously had eCS2.0/2.1/2.2 installed.


Regards

Pete

Hi

I'm not sure about the suggestions.  I have Airboot res-installed, Windows 10 booting and ArcaOS 5 failing to boot when you select it from the airboot list. 

This is how ArcaOS Maintenance Boot sees the partitions.

X: drive (ArcaOS) does not get recognized as JFS by the tool.

Do you suggest to install MBR again?

Hi

Since Windows 10 is working on this dual boot configuration, I check the W10 partition manager and check how it recognize the non-working ArcaOS partiton (which was JFS). It recognize it as NTFS, and to test I assigned it a letter and it was mounted on W10 as as working drive.

Maybe this mean that, even that I told Windows 10 to install on the first partition (selecting the custom install), it took the ArcaOS partition (JFS) and format it as NTFS.

Now I will try to reinstall ArcaOS on the 20GB X: drive and see what happens.
