I have a Viewsonic Viewpad 10, which dual boots into Android-x86 1.6 or windows 7. It defaults to booting into Android and I would like it to either default to booting into Windows or to default to booting into whatever it booted last. It uses Grub for its boot menu. I have found info on changing defaults both on the web and EE but they talk about a file in a 'boot' folder in ubuntu. I dont have ubuntu, just Windows 7 and Android 1.6.
The boot menu gives the options of pressing 'e' to edit the commands or 'c' for a command line. can thedefaults be set using either or those option?

No.
You can only temporarily edit in the Grub command line. Whatever you do there, it will only be valid for the present boot process.

If you wish to change the boot preference, you will have to edit a file inside Android.
To my knowledge, Android still uses the old Grub Legacy, so the editing should be easy:
-Find the file /boot/grub/menu.lst and open it in an editor.
-Look for a line like
 default 0
-The number behind default refers to the entry in the boot menu, beginning with '0' for the first entry.
-Set this to reflect your preferred entry
-Save the file

Note: Be very careful when editing; a misconfigured menu.lst will make your system temporarily unbootable. Best would be to first make a backup copy of the existing file before editing; you can do this with this command on the terminal:
cp /boot/grub/menu.lst /boot/grub/menu.backup

Since I don't run Android myself, I had to do some more research.
It seems to differ somehow from other Linux flavours.

You may not find the menu.lst file in /boot/grub, but in /grub.
If you still can't find or edit the file, check whether this thread (see post 3 and 4) might help:
