particularly on mixed ide, sata, usb connected drives what is seen by one kernel as sda may be sdb or sdx as seen by another kernel.
is your bios set to run hard drives in ide, ahci, or raid mode? lspci output suggests ide is enabled. recommend ahci.
<*> AHCI SATA support
<*> Intel ESB, ICH, PIIX3, PIIX4 PATA/SATA support
<*> JMicron PATA support
Don't enable:
< > Intel PATA old PIIX support
< > Intel SCH PATA support
They may interfere.
lspci -k run from the cd system will show the driver in use by the cd system.
parted -l | wgetpaste may be helpful

pav1uxa,
| Code: | | ... unknown-block(8,4) |
tells that the kernel can see sda4 but not read the filesystem that is found there.
Either your root filesystem driver is not available to the kernel or you have several HDD attached and what your kernel sees as sda4 now is not the drive you intalled on.
It looks like grub2 is trying to use UUIDs to define the root filesystem, so it should work even if drives have been swapped around.
Your ext4 options look a bit agressive.
| Code: | CONFIG_EXT4_FS=y
CONFIG_EXT4_FS_POSIX_ACL=y
CONFIG_EXT4_FS_SECURITY=y
CONFIG_EXT4_DEBUG=y |
You really don't want debug on unless you are doing ext4 filesystem development.
You probably don't want | Code: | CONFIG_EXT4_FS_POSIX_ACL=y
CONFIG_EXT4_FS_SECURITY=y |
either.

Enabled AHCI, but did not help. With this option, the computer is loaded longer

I suspect your storage controller drivers may be getting initialized in a different order so the disks are numbered differently. I would recommend trying to change root=/dev/sda4 to a PARTUUID option. Run "blkid" to get the PARTUUID corresponding to rootfs, then change the root= parameter to something like:
root=PARTUUID=d0e9ba19-5f59-4faf-9bab-14699e775d1a
Note that you must remove the "" that is shown in blkid output, it should be unquoted like my example above. Give that a try and let us know how it goes |

pav1uxa,
Its unfortunate that all your drives have a partition 4.
| Code: |
Disk /dev/sda: 80.0GB
Number Start End Size File system Name Flags
4 4432MB 80.0GB 75.6GB ext4 rootfs
Disk /dev/sdb: 250GB
Number Start End Size File system Name Flags
4 112GB 250GB 138GB extended
Disk /dev/sdc: 8053MB
Number Start End Size File system Name Flags
4 131kB 8053MB 8053MB primary fat32 boot |
The kernel can see the fourth partition on any of them.
Be aware that BIOS drive order and kernel drive order are only loosely connected, if at all.
The kernel will scan the PCI bus in numerical order, which is
| Code: | 00:1f.2 IDE interface: Intel Corporation 82801JI (ICH10 Family) 4 port SATA IDE Controller #1
00:1f.5 IDE interface: Intel Corporation 82801JI (ICH10 Family) 2 port SATA IDE Controller #2
03:00.0 IDE interface: JMicron Technology Corp. JMB368 IDE controller |
all other things being equal. That means that your PATA drive is unlikely to be sda as its attached to the JMicron controller.
Most BIOSes do something similar, however a few brain dead BIOSes, particularly in mixed IDE/SATA systems report the boot drive, whatever it is, as (hd0).
This ensures that your drive mapping changes between install and reboot and makes it particularly hard to get the boot loader install right.
The test for this is easy but fixing it is harder. Only connect your 80G drive.
It might just boot now. If not, get into your chroot and reinstall grub to the MBR. If you are using a USB stick as the boot media, ensure your HDD is sda.
Reboot to test.

Now it works, thank you
But grub2-mkconfig will fix it? |

No, but it will do it, look into /etc/default/grub for GRUB_DISABLE_LINUX_UUID |

GRUB_DISABLE_LINUX_UUID won't help here.
pav1uxa: You can try re-running grub2-mkconfig and I think it will detect root=/dev/sdb4 this time and start working, although in the future it's always possible the drive orders will switch again.
Unfortunately grub2-mkconfig can't handle root=PARTUUID= yet. It can handle root=UUID=, BUT that requires that you boot with an initramfs. In fact, if you had an initramfs, grub would automatically use root=UUID=... the GRUB_DISABLE_LINUX_UUID option is used to keep grub from automatically using this when it finds initramfs. |

Yep, it works with root=/dev/sdb4... Thank you man.
solved. |
