grub on obsd

[dennky]

I install grub from ports and then run grub-install --no-floppy sd0 (my disk is sd0) but got error "Format of install_device not recognized". I try also with grub-install --no-floppy hd0 "The file /grub/stage1 not read correcty.". Also i try with /dev/sd0 and /dev/hd0 but nothing "Not foundor not a block device".

Read the instructions in /usr/local/share/doc/grub/README.OpenBSD very carefully.

Specifically, make careful note of the example shown for using grub-install. If "hd0" fails, then try using a raw device, such as /dev/rsd0c.

I read and make menu.lst. dmesg tell me "/dev/rsd0a: file system is clean; not checking" and df "/dev/sd0a ************** Mounted on /" and fdisk sd0

0: E8   <Unknown ID
1: 01   DOS FAT-12
2: 00  unused
3: 3F  <Uknown ID>

I try grub-install --no-floppy /dev/rsd0a and /dev/rsd0b and /dev/rsd0c "The file /grub/stage1 not read correctly".

The MBR partition table you posted looks damaged.

1) Post the output of "# fdisk sd0"
2) Post the output of "# cat /grub/device.map"
3) Post the output of "$ dmesg"

Please use [code] and [/code] around each, to make them readable.

One should not attempt multibooting without a good backup!

I noticed just backup data and reset mbr then i will try to install grub.

I installed grub pt is was the problem. Create menu.lst

default 0
timeout 5
title OpenBSD
root (hd0 ,1)
chainloader +1

cat /grub/device.map

 (hd0) /dev/rsd0c

But when boot i got message

 Error 11: Unrecognized device string

Hot to modify now menu.lst ?

[jggimi]

As requested already, please post the output of:

• # fdisk sd0
• # dmesg

and, now that I discover you have a second disk, post the output of:

• # fdisk sd1

[dennky]

sd1 is usb. fdisk sd0

 0: 07
*1: A6
 2: 07
 3: 07

In dmesg for disk

 sd0 at scsibus0...
