Can't boot Live CD?

I just tried downloading the 4.0 ISO & burning it to a CD. Seemed OK, but the CD won't boot in either of my HW configurations.

One is an Acer 5536, with a GT20N optical drive

The other is an MSI Wind U100, with an external drive, GDR8081N

I'm trialing lightweight distro's at the moment, and both these hardware setups have worked with Puppy & TinyCore.

Can anyone advise? I assume I've missed something "obvious" - but it isn't to me.

Thanks

Re: Can't boot Live CD?

"CD doesn't boot" is not enough to understand what is going wrong.

Giving more info (link to iso file you downloaded, error message, steps to reproduce, print screen, etc...) would really help to understand the problem.

Happy slitaz.

Re: Can't boot Live CD?

Fair enough -

Here's the link: http://www.slitaz.org/en/get/#stable

To reproduce: insert CD in drive & reboot machine. Machine ignores CD and runs off to boot some other OS from some other drive. Note that a Puppy or TinyCore CD in the same drive will boot, so it's (probably) not the search order. I've also manually intervened in the bootloader to ensure that the CD gets visited first.

There are no error messages.

(I could print a screen, but I wouldn't want to pollute a unix forum with a windows screenshot)

Re: Can't boot Live CD?

- How about other bootable CDs you have? Do they boot?

  If not, check the drive settings in your BIOS.

  The CD drive must be the 1st bootable drive.

- Did you check the integrity of the downloaded ISO?

  Did the MD5 sums match? If not, download it again

  and make sure the ISO image is ok.

- Does the SliTaz boot procedure hang? Try to catch

  what you're reading on the screen and post it here.

Re: Can't boot Live CD?

I guess something must be wrong with the burning process or the ISO file or the CD_disk.

- Did you burn your Slitaz_liveCD using the same method when burning your Puppy_LiveCD?

- make sure the ISO file is not corrupted.

- is it possible for you to test your Slitaz_liveCD on another computer?

Re: Can't boot Live CD?

Please, detail tool(s) and procedure used to put SliTAZ on the CD before inserting it for boot, what you saw or did before another OS started, and which other OS(s) are currently on which partitions (which Windows - Vista/7/...? 32/64-bit? Home/Pro/...?).

Have you tried media other than CD? Is fingerprint protection active and working?

Something obvious may indeed be hiding in some omitted detail.

Re: Can't boot Live CD?

Darjeeling: Yes, the Puppy & TinyCore CDs (all made with he same process) boot successfully to OS in the same hardware configuration. The MD5 is the same. The boot procedure doesn't hang - it just ignores the SliTaz CD and goes on to load the C drive OS.

totoetsasoeur: Yes, I have used the identical method for all 6 CDs - one each for Puppy Slacko, Puppy Wary, and TinyCore 4, plus 3 Slitaz CDs to ensure there wasn't a physical media problem. The MD5 checksum matches. Do you mean a 3rd PC? It already doesn't work on the 2 detailed above?

Somewhat Reticent: OK, I downloaded the Slitaz iso from the link given above using Chrome on a 64-bit Windows Home ACER laptop. I used Fastsum to check the MD5 (it matched). I used a utility program called NTI Media Maker to burn the file to a CD. I used NTI's "Data Disk" option to perform the burn. (this is the identical procedure followed for the -working- 2 Puppy & 1 TinyCore CDs) The CD's are manufactured by TDK.

On both the ACER and the MSI I have tried both allowing the default bootloader process (which is set to CD, USB, HArddrive on both machines) to run, as well as intervening at the "Press F2 key now for Boot options" phase to ensure the CD drive was selected. During the default procedure, I can hear the CD drive fire up, before the boot process wanders off to the hard drive to start Windows. This is true for both the CD drives used, on both the machines.

The ACER machine has Windows 7 Home 64-bit on a non-partitioned hard drive. The MSI has 32-bit Windows 8 Developer and Customer Preview on a partitioned hard drive in the default location as per the W8 install.

I have previously booted other OS (Chromium, TinyCore 2) from USB on both machines.

I don't use fingerprint protection.

Re: Can't boot Live CD?

@tejjyid

I used NTI's "Data Disk" option to perform the burn.

The slitaz.iso is burned as an image not data.

What files are on the slitaz live cd you burned when you look at the disk in windows explorer?

If you burned as data all you will see is the iso file,which won't boot.

If burned correct as image:

[c]drwxr-xr-x  4 root root 2048 2012-04-10 16:49 boot
-rw-r--r--  1 root root 2633 2012-04-10 16:44 index.html
-rw-r--r--  1 root root 3248 2012-04-10 16:49 md5sum
-rw-r--r--  1 root root  878 2012-04-10 16:44 README
-rw-r--r--  1 root root 1217 2012-04-10 16:44 style.css[/c]
On windows install Imgburn http://www.imgburn.com/

Test the slitaz disc that fails with ImgBurn => Verify disc

It will fail if you burned as data.

Burn a new disk with ImgBurn at the slowest speed=> Write image file to disk,check the Verify box

Re: Can't boot Live CD?

1- Boot any Linux and check your cdrom

# mount /dev/cdrom /some/where

# cd /some/where

# md5sum -c ./md5sum

2- SliTaz 4.0 iso have a tiny bug. The are not hybrid (except loram flavors). All 3.0 are hybrid.

Try http://mirror.slitaz.org/iso/4.0/flavors/slitaz-4.0-loram.iso

If it works you fix slitaz-4.0.iso image with

# isohybrid slitaz-4.0.iso

Re: Can't boot Live CD?

Thx Mojo, I don't know why NTI navigated this problem for the Puppy & TinyCore ISOs, and not the Slitaz ISOs, but it didn't and imgburn did the trick. Actually, that's a pretty nice utility, thx for that link also.

Now, on to get wifi working...

Much appreciated
