Hi -

Is it possible to force dismount the system volume (named c:\ in XP but x:\ in BartPE)
while in BartPE running from a RAM disk B:\ on the hdd,
(as set up by Shirin's tutorial on Boot Land here :
http://www.boot-land.net/forums/index.php?showtopic=4866
[/code]
Reason/problem-challenge - I use Drive Snapshot,
and it will CREATE an image while booted in RAM,
but won't RESTORE an image because it says the system volume (x:\ = c:\) is still in use -

as evidenced by the failure of chkdsk c: /f from BartPE in RAM
(error message - system volume still in use)

edit > actually, cmd.exe is running FROM the system partition! x:\minint\system32\

I don't know if Shirin's method is incomplete -
maybe it doesn't create a full or true RAM drive?
is this possible? after all, it is installed on the (x: = c:) system partition?

Understand that DS will RESTORE an image when booted from my BartPE CD.
It will also RESTORE an image "at next boot" ,
when that option is selected from the app while it's running in XP -
after reboot the machine goes into DS's RESTORE mode that has a blue screen window like chkdsk does.

Others have said that Macrium Restore will both CREATE & RESTORE images
whilst booted from a hdd RAM BartPE or LiveXP.

In fact, after I get this sorted out & gain some understanding
about how/why this is/isn't working, I aim to try one more time w/ LiveXP.

My BartPE RAM disk by Shirin's method boots in 25 sec. on
XP.Pro.sp3 Intel Celeron 2.0 GHz/2 GB RAM/7200 rpm IDE

the boot CD takes 2min 50 sec

I only keep the OS on the system partition, no data,
so images are ~2.75 GB & restore in 3 minutes or so.

However I need to get there, my goal is to create a hdd-based RAM boot
from which I can run Drive Snapshot to both CREATE & RESTORE from @ very fast speeds,
given my 5 yr old machine.

Thank You for any helps

from this i guess u r running bartpe from HDD i.e u installed on hdd and it is using RAM disk B:

in this case u cannot dismount x: because that is the drive u have booted from

either boot from bartpe cd or make pe boot from ram

or make pe boot from ram


is there a different/better way of booting from RAM?

i thought i am booting from RAM :dubbio:

edit > the beginner's mind gets confused, thinks sometimes that A = B

from sj07's post, i starting to think that i'm not booting in RAM at all!
i'm booting an image, from the hdd, located on the system partition,
which will not kill it's own self by shutting down!

but still, i'm booting from the hdd, not RAM ! ? !

and a RAM drive gets created and labeled B:\ ..... why? what for?

so now i probably need to learn how to either :

1) create & install a bootable image (BartPE/LiveXP/...whatever) on another primary partition,
so that i can RESTORE images to a system partition that's not in use, eh?

or

2) learn how to create a true RAM booting image

* kindly direct me to the threads a beginner can accomplish :thumbup:

... & whilst posting, sj07 suggests firadisk, which i was recommended to earlier, thx you :thumbup:

Any of the projects here will fully load to RAM by default. I often boot to an ISO on my C: (boot drive) and then format/re-image that C: partition (deleting the ISO obviously) and can still use the LiveXP unhindered from RAM. The key is to fully load the image to RAM, some setups will only partially load to RAM, still accessing files in the ISO image which 'locks' the partition it's sitting on.
