Cd_rom booting error 7B

[panyul]

Dear all,
I have create a pre_FBA CD, but After booting the Post-FBA El Torito CD,
the error "Stop 0x0000007B(0xF7AC4640,0xC0000034,0x00000000,0x00000000)" is
displayed.
my target system :
one disk(40GB), C: 550MB,D:10GB, the last space is unallocated ;
one cd-rw
and so on;
I use tap.exe to get the target system info
I have added all the components: EnableAutoLayout,El Torito CD,EWF NTLDR,
EWF.
all the steps are from MSDN.
my design system is same as my target system,except two different type of
disks.

Have i explained my steps clear?
i have no idea about this result,Can you help me ?
Thanks!

panyul,

I don't think you gave us enough info on the steps. You should describe
presicely what you have done.

Have you run etprep.exe to swap the drive letters?

hello ererybody, hello KM,

my steps:
1. Design image,Add components;
2. Building an El Torito Run-Time Image;
3. Create Bootable CD, that is pre-FBA CD ;
4. Booting pre-FBA CD, FBA phase Begins;
5. Running Etprep.exe;
6. Create E1 Torito CD
7. Finish
then my error occur at the 4th step, and Fbalog.txt is not created yet.

error 7B means a critical boot device is missing from configuration;
but i think i have Added all hardware;

what can i do now?
Thank you for your notice!

Hello,

4. Booting pre-FBA CD, FBA phase Begins;

Where did you dig out this step?

AFAIK Eltorito CD should be present in drive while you do FBA on HDD (not on
CD)

Slobodan

panyul,

Step 4.. You need to boot the run-time image located on the 650 MB hard disk
partition (not boot the pre-FBA CD).
But as Slobodan pointed out the pre-FBA CD should be inserted into the
device CD-ROM drive.

[panyul]

hello all
thank you Slobodan
thank you KM

Now i have booted the run-time image located on the 550 MB hard disk ,and
inserted the pre-FBA CD,but got a error: 0x80004005;

i have failed to clear this error, Can you help me again?

First why is the signature of el-torito disk 0x7FFFFFFF?
Is should be 'ELTO' written in HEX.
Have you used hd2iso for creating image file?

Also your EWF is failing.
Safest way to overcome this would be to delete D:
and all hidden partitions (EWF partition from previous attempt).

use diskpart to see and delete that hidden partition.

Slobodan

[panyul]

Thank you Slobodan!

i'll try as you said.
yes, i have used hd2iso for creating image file.
but i am not understand why should the signature of el-torito disk be
'ELTO' written in hex?

 

[KM]

panyul,

The default Eltorito CD signature is 0x4F544C45 or 1330924613 in dec. This
is 'ELTO" reversed in hex. This is probably what Slobodan meant.
When you add "El Torito CD" component in to your image, there is a default
signature value in the component settings. Hope you did not change it.

Also, you may use Etprep.exe with the /delete option to clear all previously
created EWF volumes on the system.

KM

 

[KM]

Sorry, forgot to mention that you can change the default Eltorito CD
signature value in TD as long as you make sure to use the same signature
value in hd2iso (Option 5/Advanced Options of ISO Image menu).

KM

 

[Sean Liming \(eMVP\)]

Looks like you have a number of issue to resolve. From the thread - make
sure you have enough space for the EWF volume to be setup during FBA. Make
sure you have the EnableAutoLayout disabled.

There is a book with the complete steps for booting from CD-ROM: Windows XP
Embedded Advanced (www.rtcbooks.com)

hello all
thank you Slobodan
thank you KM
thank you Sean

i see and now i have booted the run-time image with no error!
i have deleted all patitions except the primary active patition c.
after my taget system booted,there are two patitions: c and d;
And new questions coming:
1. runing: ewfmgr.exe
result:
Volume Size 64512
segments 0
segment size 0
free segments 0
Max levles 1
Max protected voulmes 1
protected volume 1
Ewf volume percent full -1.#J
Protected Volumes
Device Name "\Device\HarddiskVolume1"[c:]

Is it an error: Ewf volume percent full -1.#J ?
and this line should be : Overlay volume percent full 0.00 ?

2. runing ewfmgr c: -enable
but i am not know how to check!

3. what should i do next step?
1th: install my software,such as office2000, sql, etc.
2th: etprep.exe /all to delete ewf partitions and swap volume;
3th: burn the post-First Boot Agent (FBA) run-time image to CD
4th: finished
can you tell me what i should notice at these steps?

Thank you for your notice!

hello all:

i have created my post-fba cd,and it run well.
now i found some problem:
when i run my target system from post-fba cd with hard disk,
i run ewfmgr.exe, and found the result is : unable to find an Ewf volume,
but if run "ewfmgr.exe d:",the result is :
Protected volume configuration:
type ram
state enable
volume ID: 54 00 ...
Device Name "\device\harddiskvolume2" [D:]
max levels 1
clump size 512
current level 1
memory used for data 2950656 bytes
memory used for mapping 4096 bytes

is there any errors?
thanks!

[KM]

panyul,

I don't understand you post. Could you read and correct it?
Specifically, what "ewfmgr.exe" command you test? What you expect? What you the problem?
You seem to protect a second volume in your system and this is all I can say from your message. If it is not what you want, go to
your TD configuration and check "Enhanced Write Filter" component settings.

£¨Booting the Run-Time Image from an El Torito CD£© After the
post-First Boot Agent (FBA) run-time image is burned to CD, it is ready for
¡¡deployment. You can boot your CD-ROM on any system that supports bootable
CDs. Verify that Enhanced Write Filter (EWF) is operational after booting.
(From
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xpehelp/htm
l/xeconeltoritodesignconsiderations.asp)

i did as this article, and booted my target system susccessfully.
my target system has one hard disk with only one partition c.
but after booted,there are two partitions( c and d) .
where the another one comes from ? is it ewf partion?
but when I executed 'ewfmgr' I got the 'unable to find EWF volume'
response,i thought it was not working.
then I tried 'ewfmgr d:', the response i had shown , but 'ewfmgr c:'
returns an error.

had i explained clear?
i am sorry for my poor english!

thanks for your notice!

[KM]

panyul,

i did as this article, and booted my target system susccessfully.

Do you boot from the Eltorito CD now? or your image is still on HDD?

my target system has one hard disk with only one partition c.
but after booted,there are two partitions( c and d) .

How do you check? Just Windows Explorer or something low level (diskpart,
etc)?

where the another one comes from ? is it ewf partion?

Wndows Explorer can't see the hidden EWF storage partition (of type 0x45).
I'd suggest you to check what the second partition is and where it comes
from. If you don't create it intentionally, it can't appear by itself.

but when I executed 'ewfmgr' I got the 'unable to find EWF volume'

response,i thought it was not working.

then I tried 'ewfmgr d:', the response i had shown , but 'ewfmgr c:' returns an error.

had i explained clear?

No, you did not. You will need to describe the exact steps you did. You may
also attach your FBALog.txt here.

If you follow steps from the article with the target configuration menitoned
there, you should not have problems.

KM

 

[Slobodan Brcin \(eMVP\)]

Just to make sure if your El-torito is really working.
Disconnect HDD before booting.

If your CD does not work, then change EWF ARC path.

Slobodan
