The Bcdedit. Shows all commands one is able to use bcdedit. Create a Backup It is strongly recommended that one creates a backup of the BCD store before making any changes to it. It has limited funcionality as regards the BCD store however, with the only relevant functionalities being to change the default boot operating system, to delete a boot menu item and to change the timeout display period of the boot menu.
CAUTION: Making incorrect or invalid changes to one's BCD store can result in the system no longer booting and only those comfortable with using command line entries and who understand the inherent risks of making a mistake should do so. Advanced Options Please do not run these commands unless you know what the outcome will be. I read it multiple times, but I don't come out Point of start : A laptop, running 2 versions op XP, on two disks one is removable.
On the default version build-in disk , I have all admin-rights. The second version is pre-installed by our IT-department on a separate disk, and I 'm just al regular user. I guess it is just dropped on the disk using a Ghost-image. All boot files boot. COM are on that partition too, but to boot into this version, it was the boot. So I mean, it is not necesarry that this boot-files are on that second disk too. The more you tell us the more we can help.
Can you help us improve? Resolved my issue. Clear instructions. Easy to follow. No jargon. Pictures helped. Didn't match my screen. Incorrect instructions. For all BCD elements that hold a boolean value, any non-zero value is interpreted as true. The integer value for firstmegabytepolicy , debugtype , configaccesspolicy and safeboot is interpreted modulo 32 bits.
For debugtype , any value other than 0, 1 or 2 is an error. The options string may also contain switches to describe a RAM disk, but their derivation is not so easily described and is presently beyond the scope of this article. The affected switches are:. Not all BCD elements are translated. Some that are translated, such as pae , do not matter to the kernel or to any known HAL. Although they are loaded from the BCD store, there can have been changes already.
The active options, presented as simulated BOOT. INI switches, may be removed or added to. Note however that some options may have been acted on already, so that an option that is changed through the Edit Boot Options menu need not work exactly as if it had been determined from the BCD store.
Indeed, it need not work at all. Some of the BOOT. Mostly, one BOOT. The whole string is set as the updated value of loadoptions.
