Bootloader don't start

Hello everyone,

a few days ago i reinstalled linux from live CD.
I have kept all partitions. The only thing i have changed is '/root' and '/var' filesistem. Before i had reiserFS and now is ext4.
I formated /root, /boot, /var with mkfs.
I followed arch installation guide and installed arch with syslinux bootloader.

After reboot the laptop hangs at black screen with text edit marker blinking.
No error and bootloader screen dont show up.

After that i installed grub and the problem is the same.
Then i have installed again syslinux only this time manually - dd mbr, fdisk /dev/sda and setting sda5 (/boot) to active. No difference.
If i boot from liveCD and select "boot from HDD" the bootloader shows up and averyting is working as it should.
If i add boot flag to sda1 (windows7 partition), windows start normally widouth syslinux bootloader.
I thought that partition table is somehow corrupted, so i resized one partiton in gParted to recreate it. No difference.

My laptop is Toshiba satellite a665-11t with phoenix bios.

fdisk output:

Disk /dev/sda: 640.1 GB, 640135028736 bytes

file mbr (current mbr + partition table):

partition 4: ID=0x17, starthead 254, startsector 1227448320, 22812672 sectors, code offset 0xc0

linux:
sda5 is /boot
sda6 is /root
sda7 is /var
sda8 is /home

sda(1-4) are primary partitions
sda(5-9) are logical partitions

sda4 is windows7 OEM recovery disk

I dont know why this is happening, becouse before arch reinstall everyting worked.
Booting from liveCD and then selecting HDD is a little bit annoying.
Any help is apprechiated. I have run out of ideas.

p.s. disk dont have any bad sectors and installing syslinux/grub complete without errors. Disk has MS-DOS partition table.

Re: Bootloader don't start

Try boot with the livecd (not boot Hdd, boot the livecd) and view the configuration file the syslinux, and compare the difference with the syslinux configuration file in your Hdd installation.
If the partition table is broken, don't boot anything in the hard disk.

As you can se my syslinux.cfg is almost the same.
I only uncommented windows chainloader and changed /dev/sda3 to /dev/sda6 (i hope that this is correct).

I don't think that my syslinux.cfg is the problem becouse if i run liveCD and in liveCD syslinux screen select "boot existing OS" my installed syslinux (on sda5) screen shows up and i can normaly boot arch linux or windows on my HDD.
Widouth liveCD computer isn't able to boot from HDD - after few seconds of black screen BIOS boot selection meni is shown (boot from Toshiba HDD / boot from CDROM).

Re: Bootloader don't start

https://wiki.archlinux.org/index.php/Sy … al_Install

The manual install implies:

1) installing files (and no, I'm not talking about pacman -S syslinux; that installs the syslinux package)
2) marking the partition as active (by setting up the boot flag)
3) installing the MBR boot code.

# extlinux --install /boot/syslinux

    ^ Did you run this command? Because without it, poor little "ldlinux.sys" isn't being placed on the correct drive sector, with the correct attributes and no boot for you! But maybe you'll have more luck with the automatic method (... -iam).

Re: Bootloader don't start

I have executed above command and boot from HDD still fails.
Automatic install with '-iam' parameters doesn't work either - although it completes widouth errors/correct output message is shown.
I have installed grub boot loader before on this PC and several others and I never had those kind of problems. I hope that syslinux didn't broke something on my disk in a way that even grub doesn't work anymore.

p.s. Thank you for all replys. I realy appreciate your effort and I hope we will find solution. Repartitioning and formatting whole disk is not an option becouse this is a work computer and I can't afford reinstalling all programs, devEnvironments and data again.

Hello!

can anyone please help me with this problem.
I am still booting arch linux from cd-rom (for 5+ months).

Re: Bootloader don't start

Your boot partition is not a primary partition - I don't think this can work with sylinux and mbr.

Re: Bootloader don't start

What do you suggest then? Windows is usig 3 primary partitions.
One is recovery, one is c disk and in don't know why is sda9 used (windows was preinstalled on laptop).

Re: Bootloader don't start

I don't have much of a suggestion - you need to figure out how to manage your own partitions - I'm just highlighting what can't work (AFAIK).

You could remove windows - you could reduce windows partition use - you could use a different bootloader/partition table.  GPT partition tables do not have this restriction.

Re: Bootloader don't start

I think that grub2 can handle this correctly.  It seems to support just about any nonsense setup a user can dream up, including putting your kernel on Linux software RAID, LVM, etc.  So I would surmise that this should be no problem for grub.

Please note that it has been a long time since I have used grub, though I did do some testing of grub2 when it was very young, its craziness drove me away.  So this statement is based on what I have read from others, and not from persona experience.

Re: Bootloader don't start

You should change the "/dev/sda5" entry from your fstab to end in a "2". Everything else except the root partition should have either "2" or "0" on the last column:

https://wiki.archlinux.org/index.php/Fs … efinitions

Then you should use UUIDs in syslinux.cfg:

https://wiki.archlinux.org/index.php/Sy … sic_Config


And check the BIOS boot priority (the 640 GB "TOSHIBA" HDD with the boot partition needs to be the first one to boot).
