Hi, I'm new to the subject an installed elementaryOS on a pretty old (1,8 GHz single processor) WinXP computer. So far everything worked fine for a few days. Now when I try to boot Windows, I chose Windows in the grub list but it just flips back to elementary, which I can boot. Tried supergrub2, it finds the Windows partiton, but also doesn't boot it. Any ideas? sven
Step 1: backup! make a copy of any data you want to keep (just in case). Step 2: If you have the original windows XP CD, then you can restore the Windows XP MBR following the steps in the link below. https://neosmart.net/wiki/fix-mbr/#Fix_the_MBR_in_Windows_XP Once windows is up and working again (reboot a few times to be sure ) , you will then need to get the elementary CD again to boot into elementary OS and restore your grub configuration.
