I have install two debians and win10 in my pc.

Now i install GhostBSD in /dev/sdb2,reboot my pc, no GhostBSD in grub menu.
I have to enter into debian and run:

Code: Select all

sudo grub-mkconfig -o  /boot/grub/grub.cfg

grub-mkconfig can find GhostBSD ,but it is still not written into grub ,reboot ,the GhostBSD not in grub menu.
How can i write it into grub.cfg manually?

Here is what I do manually from the "Grub >" prompt. This might give you a hint to setup in grub.cfg file. I see using partuuid identifiers above. This is good.

from the "Grub >" prompt manually enter the following 3 items to boot rEFInd boot manager. Please adjust to your particular setup of disks and partitions. I had one USB 3.0 128GB flash drve that I installed my GhostBSD from a 2nd usb flash drive that I had booted the live image from. I booted into rEFInd boot manager and selected either GhostBSD or Manjaro from there. gpt1 is the 50 megabyte FAT32 partition, gpt2 is the ZFS partition for GhostBSD data, 120+ GB gpt3 is the 8 GB swap partition

set root='(hd1,gpt2)'
chainloader (hd1,gpt1)/efi/boot/BOOTX64-REFIND.EFI
boot

GPT
In this example, we will format ada0 with the GPT scheme and create boot,
swap and root partitions. First, we need to create the partition table:

/sbin/gpart create -s GPT ada0

Next, we install a protective MBR with the first-stage bootstrap code.
The protective MBR lists a single, bootable partition spanning the entire
disk, thus allowing non-GPT-aware BIOSes to boot from the disk and pre-
venting tools which do not understand the GPT scheme from considering the
disk to be unformatted.

/sbin/gpart bootcode -b /boot/pmbr ada0

We then create a dedicated freebsd-boot partition to hold the second-
stage boot loader, which will load the FreeBSD kernel and modules from a
UFS or ZFS filesystem. This partition must be larger than the bootstrap
code (either /boot/gptboot for UFS or /boot/gptzfsboot for ZFS), but
smaller than 545 kB since the first-stage loader will load the entire
partition into memory during boot, regardless of how much data it actu-
ally contains. We create a 472-block (236 kB) boot partition at offset
40, which is the size of the partition table (34 blocks or 17 kB) rounded
up to the nearest 4 kB boundary.

/sbin/gpart add -b 40 -s 472 -t freebsd-boot ada0
/sbin/gpart bootcode -p /boot/gptboot -i 1 ada0

We now create a 4 GB swap partition at the first available offset, which
is 40 + 472 = 512 blocks (256 kB).

/sbin/gpart add -s 4G -t freebsd-swap ada0
