jensmander Posted May 26, 2020 Share #1 Posted May 26, 2020 If you want to modify your grub.cfg of your written boot stick or want to access the partitions (adding extra.lzma from @IG-88) you can use a free portable tool. Notes: - the grub.cfg is located in the folder "grub" on the first partition (15MB) - the extra.lzma is on the second partition (30MB) 1.) Download MiniTool Partition Wizard Free Edition (portable): https://www.partitionwizard.com/download/v12-portable/pw12-free-64bit.zip 2.) Unzip it and launch the "partitionwizard.exe" with administrative rights. 3.) Plug in your boot stick. Partition Wizard will automatically recognize the new drive. In this example it is drive no. 4. Now select the 1st partition of your stick (15MB) -> rightclick and select "Change Letter" in the context menu. 4.) Select a desired drive letter and click on "OK". 5.) In the lower left pane of the tool click on "Apply" and confirm the pending changes: If everything went OK you should see a success message: Now you have full access to the 1st partition with the Explorer or your favourite file manager. If you're done with any modifications it's advisable to unmount the drive letter. The steps are nearly the same. 6.) Right click the 1st partition again -> "Change Letter" -> select "New Drive Letter: none" -> "OK" -> click on "Apply" to the lower left and confirm the changes. 5 Quote Link to comment Share on other sites More sharing options...

drapan Posted June 18, 2020 Share #3 Posted June 18, 2020 I do as explained, partitions are mounted, first partition (15MB) can't be accessed, Windows tell me "You don't currently have permission to access this folder" For the second partition, everything is ok , can be mounted and accessible from explorer. I need this to copy grub.cfg. Any idea ? Quote Link to comment Share on other sites More sharing options...

indyslim Posted June 21, 2020 Share #5 Posted June 21, 2020 Can I also use this tool to make a back up copy of the boot USB stick from a functioning DSM installation? Quote Link to comment Share on other sites More sharing options...

No, for this you would need another tool, like the "USB image tool" (freeware): https://www.alexpage.de/usb-image-tool/ 1 Quote Link to comment Share on other sites More sharing options...
IG-88 Posted April 16, 2021 Share #7 Posted April 16, 2021 beside the mounting with partitionwizard there is a better way to use the tool to get easy access to the loaders 1st and 2nd partition start the tool, right click on the loaders main entry where is states GPT, convert it to MBR, apply to execute the oüeration, do the same again but revers it, convert it to GPT and click apply now windows 10 can access both partitions as its supposed to be and you don't need any additional tools and with that its also possible to get the MBR version of the loader (often needed for HP desktop's), no need for a special download of the loader, just do it yourself @jensmander maybe you can add this in the 1st post as option? 1 Quote Link to comment Share on other sites More sharing options...
flyride Posted April 16, 2021 Share #8 Posted April 16, 2021 (edited) Nice trick. Does this work to make 1.03b loader usable on UEFI-only systems? Edited April 16, 2021 by flyride 1 Quote Link to comment Share on other sites More sharing options...

Hi I get the following error: When I click on "security tab" (opens properties but there is no Security tab) I'm trying to read the grub.cfg file to see if I made any mistake. Thank you very much in advance for your help. Best, -a- Edited July 2, 2021 by asheenlevrai Quote Link to comment Share on other sites More sharing options...

Moon Doggy Posted November 17, 2021 Share #15 Posted November 17, 2021 The above instructions didn't work for me either. Launched as admin, but get the prompt that I don't have permission to access. I also tried converting to MBR and back, still can't access it through File Manager. I could browse with the Partition Wizard, but can't access the files.
