Tricchi Posted December 30, 2016 Share Posted December 30, 2016 I completed the Sierra installation on my Dell e6530 thanks to your help in the previous post. But at every start I always the error "invalid partition table!" and pressing Enter will start correctly. How can I eliminate that mistake? I found some suggestions in that link https://osxlatitude.com/index.php?/topic/5660-dell-latitude-e6430e6530-with-nvs5200m-hd4000/?p=29476but we are talking about Chamelon and instead I used Clover. How can I fix? Link to comment Share on other sites More sharing options...

Administrators Bronxteck Posted December 30, 2016 Administrators Share Posted December 30, 2016 was the disk an MBR formatted disk instead of GUID before clover? Link to comment Share on other sites More sharing options...
Tricchi Posted December 30, 2016 Author Share Posted December 30, 2016 No, I think that was the beginning formatted partition GUID. Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted December 30, 2016 Administrators Share Posted December 30, 2016 you might have set a partition as active maybe during one of the clover installs or chameleon did. Link to comment Share on other sites More sharing options...
Tricchi Posted December 30, 2016 Author Share Posted December 30, 2016 How would I go to see this? What do you recommend I do? Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted December 30, 2016 Administrators Share Posted December 30, 2016 i guess the simplest way check is with a linux distro with gparted or disk utility. anything else in osx will probably entail terminal commands and maybe gpt fdisc. or just reinstalling the whole os after a disc wipe/ repartitioning.

Tricchi Posted December 31, 2016 Author Share Posted December 31, 2016 What kind of command I might try using the terminal to see which the problem and possibly fix it without data loss? Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted December 31, 2016 Administrators Share Posted December 31, 2016 run this command first to make sure you do not have a core storage disk diskutil cs list if it finds a core storage volume and you only have 1 disk and osx is on disk0s1 then diskutil corestorage revert /dev/disk1 you can also check to see if . the volume is blessed bless --info /Volumes/volume name/ if it returns with all zeros 0 => then it might need to be blessed wich is apple form of allowing a volume to be bootable sudo bless --bless /Volumes/Volume name/ for windows here are a few sugestions http://serverfault.com/questions/276076/how-can-i-un-mark-a-partition-as-active you can probably do it from a windows installer command prompt unsetting an active partition in osx there is no straight forward way to do it without installing windows or linux binarys made to work on osx like fdisk or gparted or gpt-sync as OSX does not use an MBR partition Link to comment Share on other sites More sharing options...
