rakibulmuhajir Posted March 10, 2020 Share Posted March 10, 2020 I have been trying to install catalina on my dell precision 5510 the whole day but i'm always stuck during boot with error "could not allocate runtime area" I followed vailla guides as well as guides specific to precision m5510 and xps 9550. I tried all varients of aptiofix. tried to find my own slide value by getting hex values of my memmap though i might not have been able to get correct value. I also tried open core alternative to aptiofix with no luck either. i read other topics and can confirm i have two ram slots occupied. bios settings are also set accordingly Any help would be appreciated Current System Dell Precision 5510 Core i7 6820 2x8gb ddr4 512GB nvme SSD Liteon Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted March 10, 2020 Moderators Share Posted March 10, 2020 Remove the following. Not from my guide /E/C/drivers/UEFI OcQuirks.efi OcQuirks.plist OsxAptioFix3Drv.efi SMCHelper.efi VBoxHfs.efi FwRuntimeServices.efi Remove FakeSMC from /E/C/kexts/Other 1 Link to comment Share on other sites More sharing options...
rakibulmuhajir Posted March 10, 2020 Author Share Posted March 10, 2020 this time i was able to proceed further with boot flag slide=151 but there is another step where it stops. Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted March 10, 2020 Administrators Share Posted March 10, 2020 right now it looks like it is stalling out on audio. disable whatever you are using to load the audio and see if you get further. 1 Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 10, 2020 Moderators Share Posted March 10, 2020 Your LiteOn NMVe drive might be causing issue. Try this Config, added a patch for the bit swap block size config.plist.zip 1 Link to comment Share on other sites More sharing options...

rakibulmuhajir Posted March 11, 2020 Author Share Posted March 11, 2020 ok. with this i was able to land on installation screen now there are two issues catalina cant be installed without internet connection. is it normal? when erasing the drive where i need to install, it fails saying Quote MediaKit reports not enough space on device for requested operation. i have single 512 gb nvme drive which i want to dual boot with windows 10. i dont want to format the drive. is there any other solution?
