![]() I just thought this story might be interesting. Boot is now normal speed, and gparted finds my 7 partitions now. it may be necessary to wipe the disk using the wipefs command before. There are two ways to work around this problem: Boot the Windows installer in EFI mode. wipefs can erase filesystem, raid or partition-table signatures (magic strings) from. If Windows is complaining about your use of GPT, that means that the Windows installer has booted in BIOS mode rather than in (U)EFI mode. Yes I had to type the whole 90 lines of wipefs. Command (m for help): d Partition number (1,2, default 2): 1 Partition 1 has been. GPT is the GUID Partition Table, which is a method of defining partitions (not protection) on your computer. ![]() So back to SystemRescueCD, and do from there wipefs -o 0x7dc00 /dev/sda Wipefs: error: /dev/sda: probing initialization failed: Device or resource busyīut, hang on, the disk is mounted and it can not do it from within Debian We can use wipefs to remove these zfs signatures as follows wipefs -o 0x7dc00 /dev/sda Sda 0x1fe lists many items that are called signatures… most of them zfs_member, but at the end my GPT partition table, another copy of the GPT partition table at the top of the disk, and the PMBR (protective MBR). Now, wipefs sounds like a dangerous tool, and it is, so another clonezilla backup first. much research, and I finally find a tool called wipefs which I can use to check the disk. What is going on? There must be some residue of ZFS on the disk?. when I looked at the disk from within Debian, with the Gnome-disk-utility, it looked normal, but when I looked with gparted it said the entire disk was one ZFS partition!.Then a reboot showed that i had a grub menu and could boot from that. So then from within Debian I could configure grub with update-grub. From there I booted Debian with grub> linux /vmlinuz root=/dev/sda4Īnd Debian booted. Here are the practical steps on the /dev/sdb drive1) Create GPT partition tableBefore creating the partition table, you should use wipefs to wipe the. Then I could reboot and get the grub> prompt. Used SystemRescueCD for that.Īlso had to remove grub.cfg from the Debian filesystem, because I had reinstalled Debian to a different partition.Īlso had to edit /etc/fstab to fix the UUID’s Went ahead with clonezilla and restored my Debian filesystem and my data filesystem. will remove the partition table stderr: wipefs: error: /dev/sdi: probing initialization failed: Device or resource busy -> failed to wipefs device. ![]() I did that with gparted…made a GPT partition table and created 7 partitions … EFISystem, bios-boot, 4 x ext4 partitions, and a swap partiton. So I had to put the partitions back before I could restore filesystems. They were saveparts images - ie images of partitions. It wrote a ZFS filesystem all over my 500Gb SSD… wiped everything, even grub on the MBR.įortunately I had clonezilla backups. I was looking a TRUEOS DVD and I thought it was a live system, but it was an install DVD.
