Hi
first of all many thanks for easybcd. Its a great piece of SW.
It helped me for a co-existance of Win7, XP and FreeBSD.

I encountered the following problem.

I want to enable the bootoption /PAE for my 2nd OS on disk Windows XP SP3 32-bit.
If I enter under windows 7 "Advanced Settings", then all entries under the Tabs
"Advanced" and "Developer" are "greyed-out" and can not be used.

I read the FAQ + Tips and Tricks section, but didn't find any helpful tip.

Note: I am running easybcd on windows 7 as normal user without admin privs.
But the system detects that admin rights are required, so upon start of easybcd
I get asked for the admin password.
So far so good, and this way I have no problem to manipulate the bootoptions at least.

Thanks for any hint.

Hi donjo, welcome to NST.

You can't configure advanced settings in EasyBCD for anything older than Windows Vista.

To disable PAE you'll need to open boot.ini and add
Code:
/NOEXECUTE=ALWAYSOFF
to the end of the line for the OS.

I tried this now as Administrator under Win7.
Same result. Can't enable PAE as entries are shaded.
EasyBCD version is 2.0.1.111
OS: Windows 7 Home Premium

Addendum:

Hi, thanks for your quick response.

I would like to have 2 separate entries with the Win7 based boot manager.
One to boot XP with and without PAE

I already created a 2nd boot entry with easyBCD, see entry 3.

There are a total of 4 entries listed in the bootloader.

Default: Windows 7
Timeout: 5 seconds
Boot Drive: C:\

Entry #1
Name: Windows 7
BCD ID: {current}
Drive: C:\
Bootloader Path: \Windows\system32\winload.exe

Entry #2
Name: Microsoft Windows XP
BCD ID: {ad1d01b2-91fa-11df-bc13-fc8975a797ce}
Drive: C:\
Bootloader Path: \NST\ntldr

Entry #3
Name: Microsoft Windows XP PAE
BCD ID: {ad1d01b4-91fa-11df-bc13-fc8975a797ce}
Drive: C:\
Bootloader Path: \NST\ntldr

But when looking at boot.ini, I still only see one entry for booting XP.

; This boot.ini was automatically generated by NeoSmart Technologies' BootGrabber.exe
; Use EasyBCD from Download EasyBCD 2.0.1 - NeoSmart Technologies to manage your bootloader

[boot loader]
timeout=15
default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Windows XP on I:\" /fastdetec
If I would add now one additionally entry in boot.ini like this, would
Entry 2 in easybcd/win7bootmenue boot XP without PAE and
Enrty 3 in easybcd/win7bootmenue boot XP with PAE

Or how is the dependency between entries in EasyBCD boot menue and boot.ini ??

Thanks for any pointer

Delete your Windows XP entries.

Create 2 new Windows XP entries in EasyBCD, but *explicitly* specify the drive that Windows XP is installed to (i.e. don't use the autoconfigure checkbox).

You'll find a ebcd.001 and ebcd.002 file on your disk. Each one is for a different entry.

Addendum:

Obviously then you can add the noexecute line to whichever file you like.
