What you said about merging partitions bothers me, so, how did you "merge" the partitions? Have you tried assigning a drive letter in disk manager?Sun, 06 Apr 2008 02:59:54 GMTWAW8http://www.vistaforums.com/Forum/Topic81368-44-1.aspxwell, the drive doesnt show up in explorer. it shows up in disk manager as a drive, but without a letter.Sat, 05 Apr 2008 20:00:32 GMTandrewbt1991http://www.vistaforums.com/Forum/Topic81368-44-1.aspxHow did you determine that the partitions disappeared? Did you use an app like Disk Director that shows all the partitions on the drives, even the hidden ones? OR did you rely strictly on drive letters that showed up in Explorer or Computer?Sat, 05 Apr 2008 19:15:28 GMTWAW8http://www.vistaforums.com/Forum/Topic81368-44-1.aspxthe other day i wanted to dual boot my Acer laptop. it came with Vista home premium 32bit, and i wanted to use XP as well. but something went wrong with the install and XP didnt work. then the partition that had XP just disappeared. then my D:\ drive disappeared. i used my vista ult. x64 boot disk that i use for my desktop computer and merged the 2 missing partitions and then D:\ came back. then when i booted my laptop up this morning D:\ went missing again! any idea of what is happening?Sat, 05 Apr 2008 18:40:27 GMTandrewbt1991
