The most effective combinations either BIOS+MBR or UEFI+GPT. You could go around that, but it is not recommended at all.
The most compatible combination is
UEFI + GPT + Fast startup disabled + Secure boot disabled
If manufacturers stay sound, Secure boot will keep working with most Linux distributions but the future is unknown.
The steps are:
A detailed guidefor multibooting is here:
It’s a “problem” that often happens accidentally, but is also used intentionally to prevent copying and indexing of PDF files, especially when posted online.
Fonts in PDF files are stored with two tables, one contains the glyphs (the character shapes) and one contains a “toUnicode” map, which says what character each glyph represents. Acrobat uses the first table to draw the page, so it doesn’t actually know what the text “says”, only which patterns of shapes to draw. When you copy or search the file, the second lookup table is used to work out what the text says (i.e. in the word APPLE the first table says the second shape looks like “P” even if the shapes aren’t stored in alphabetical order, the toUnicode table says the second letter is 0x0050, a capital P).
If this toUnicode map is corrupted or missing, the PDF will render to screen (and print) just fine, but Acrobat has no idea what the shapes mean. The result when you screenread, export, search or copy/paste is a default set of mappings – so it will be a 1:1 relationship (every “A” will become the same character) – but the pairing is not predictable, so it cannot automatically be repaired. You can do it using plugins but would have to manually work out what each pair should be, and recreate the map table a letter at a time.
When this happens intentionally, it means the document author has removed or re-written the toUnicode map, using a plugin. When it happens accidentally it usually means the software exporting the PDF didn’t pass the correct font information to the PDF print driver (in the PostScript stream).
Here are the solutions:
You need Acrobat 9:
To create a junction you can use the following command from a terminal:
mklink /J C:\...\linkname C:\...\OriginalFolder
To add a GUI, you can install the shell extension from:
You perform the following steps:
Then, instead of copy and paste, you use pick and drop to create junctions and links:
