I have dual boot with win98 and xp.
I installed Avast on the the xp side and
now my machine gets a windows protection error
when I try to boot to win98.
XP side boots fine.
I have Norton installed on the 98 side.
Thanks

Its never a good idea to have two anti-virus programs at the same time, or they will conflict (is most likely what has happend in your case), you will have to choose between Nortan anti-virus and Avast anti-virus.

Lee, they are not running at the same time, they will be on seperate partitions on a dual boot system there is no conflict as there is only one AV in each OS partition.
@ rx74me
If you could post the error, perhaps it may give us a clue.
Have you scheduled a boot scan in XP that hasn't been run that might somehow be getting in the way of the dual boot.
Have you ever had this working?
Is this something that has just occured, r has it been like this since installing avast?
Have you installed/updated anything recently that could have had an effect?
Sorry I can't be more helpful, I don't use dual boot.
-
From your working XP partition, you could run msconfig and disable avast! from starting and reboot to see if that gets you into 98.
Perhaps a paste of xp's boot.ini file (under xp again) might help also. I dual boot but with linux so not too sure if this will help, but it should show up any obvious faults in the boot loader at least.
-
My dual boot has always worked.
The only thing I can think of , is installing avast.
I have 2 machines where it does not boot anymore
into windows 98.
Of course I didn't think of checking the dual boot
after installing Avast till I needed to actually boot to win98.
I can boot win98 in safe mode. :-X
-
What is the exact error you are getting when trying to boot 98 normally?
-
I dual boot but with Linux
Me too 8)
Which antivirus do you use on Linux partition?
-
Probably way out of the ball park here rx74me, is Xp using SP2?

Replied by private msg ;)
-
I'm using sp2 on xp.
I did safe mode boot into 98 and bypassed ndis.vxd
and it boots.
I don't understand why this is happening especially
when it was working before.
It's doing this on both my machines. :(
I may just have to reload win98 on my son's computer and chunk
xp since not all his games run on it.
-
Perhaps this can help you.

I'm running the 1st edition of win98.
Should I load it anyway?
-
Probably won't work. Bu I have an idea that with a bit of luck might work.
- Boot in safe mode
- Remove the modem/NIC from device manager
- Try to boot normally
- Reinstall the modem/NIC

I'm not that good in Windows 98 but the second edition (SE) isn't a must have update?
To Vlk and other programmers:
Does avast change anything in MBR or boot sector?
Why some applications (like Symantec GoBack, which indeed change MBR) conflict with avast?
-
To my knowledge, Avast does not change the MBR in anyway. But Avast does need to reed the fat on some occasions. e.g. when using the BART cd.
hmm now that I think of it, does the bootscan on NT based systems needs a non altered MBR also?

If you mean the boot time scanning, no. I can use it with a changed MBR (I use GAG for dual booting into Windows and Linux). Boot time scanning works like a charm.
But, GoBack is incompatible with avast is some systems... I know Vlk will say GoBack is buggy... Vlk, can you say me something? Can I make them compatible? Can you show me the way? :-*
