Windows 7: restoring SEVEN boot in dual boot XP/SEVEN

restoring SEVEN boot in dual boot XP/SEVEN

I am using Win XP + 7 in dual boot, because there was a program that did not run well on Win 7, only on XP. After a thousand experiments, could make it run well on Win 7. I now want to uninstall XP. Can I do this with the partitioner, formatting the partition that contains XP.
I am in doubt if it will not make me lose the boot of Win7.
If this happens, the commands fixboot and fixmbr work? ... There are other commands for this?

Just in time: Microsoft says in SEVEN Help: You can not uninstall an old OS without damaging SEVEN...

We help do them here every day.

Please post back a screenshot of your full DIsk Management drive map so we can advise you better of the needed steps. Use the Snipping Tool in Start Menu and attaching the file using paper clip in reply box.

You will need the excellent tool EasyBCD. Please install it to also include a screenshot of its front-panel listings.

Hi Jaca! Welcome to SevenForums! If you installed Seven first, then all of the boot and MBR files are on Seven's partition and wiping XP will not affect the MBR.

warning   Warning
If you still have an XP option at boot, download and install EasyBCD, choose Add/Remove Entries from the Sidebar, select XP from the list and click delete. When you reboot XP shall be GONE!

I made the removal of XP through EasyBCD and then formatted that partition. Okay. The next step was to merge the two partitions (seven + XP) and then everything stopped working. The only alternative was a complete reinstallation of the Seven. It gave work, but is well now

Sorry you didn't post back the requested screenshots of Disk Management and EasyBCD listings. We could have advised you the easy steps. We do this every day here.

We would have shown you how merging or resizing operations require the partition to be marked active first, then boot into the Win7 DVD to run Startup Repair 3 times to repair the MBR which has been moved.

Jonathan.............. Why do you need to do it three times? I had to do it 3 times myself once, but I never understood why???

As I understand it: Startup Repair in Win7 automates all bootsect and bootrect recovery commands, but only runs them after completing all of it's myriad tests and fixes. You can see the list on the log it produces when prompting for reboot.

It assumes that a given fix will work until the user returns for another.

So it may run all tests, then run bootrec /fixboot + bootrec /fixmbr, prompt for reboot.

However in a dual boot extraction where MBR has been removed, this may not be enough so it will next run bootsect command which will normally start Win7.

Win7 will often restart in two reboots in above scenario, however Startup Repair may have found another issue and tried a repair earlier not related to bootrec and bootsect so it can often be three total times before it works.

When no installation shows to repair, Startup Repair will sometimes not work. I have gotten it to discover the installation to repair by manually running the bootrec and bootsect commands. Strange, but true.
